EXPERIMENT # 2
OBJECT: Verify the Thevenin’s and Super position Theorems for dc circuits.
THEORY:
THEVENIN'S THEOREM
Thevenin's Theorem states that it is possible to simplify any linear circuit, no matter how complex,
to an equivalent circuit with just a single voltage source and series resistance connected to a load.
Thevenin's Theorem is especially useful in analyzing power systems and other circuits where one
particular resistor in the circuit (called the “load” resistor) is subject to change, and re-calculation
of the circuit is necessary with each trial value of load resistance, to determine voltage across it
and current through it.
Example: find the voltage across R2
Fig.2.1
Thevenin's Theorem makes this easy by temporarily removing the load resistance from the original
circuit and reducing what's left to an equivalent circuit composed of a single voltage source and
series resistance. The load resistance can then be re-connected to this “Thevenin equivalent
circuit” and calculations carried out as if the whole network were nothing but a simple series
circuit.
Fig.2.2
First, the chosen load resistor is removed from the original circuit, replaced with a break (open
circuit):
Fig.2.3
Voltage between the two points where the load resistor used to be attached is –
12

Fig.2.4
Thevenin voltage” (EThevenin) in the equivalent circuit = 11.2 volts
Thevenin series resistance- With the removal of the two batteries, the total resistance measured at
this location is equal to R1 and R3 in parallel: 0.8 Ω. This is our “Thevenin resistance” (RThevenin) for
the equivalent circuit
Fig.2.5
Now current through R2
I= Eth/(Rth + R2) = 11.2/2.8 = 4 amp
Voltage across R2 is : I x R2 = 8Volts
SUPERPOSITION THEOREM:
The strategy used in the Superposition Theorem is to eliminate all but one source of power within
a network at a time, using series/parallel analysis to determine voltage drops (and/or currents)
within the modified network for each power source separately. Then, once voltage drops and/or
currents have been determined for each power source working separately, the values are all
“superimposed” on top of each other (added algebraically) to find the actual voltage drops/current
with all sources active.
Fig.2.6
Case (i) Consider 28 V source only
13

Fig.2.7
Case (ii)Consider 7 volt battery -
Fig.2.8
When re-drawing the circuit for series/parallel analysis with one source, all other voltage sources
are replaced by wires (shorts), and all current sources with open circuits (breaks). Since we only
have voltage sources (batteries) in our example circuit, we will replace every inactive source
during analysis with a wire.
When superimposing these values of voltage and current, we have to be very careful to consider
polarity (voltage drop) and direction (electron flow), as the values have to be added algebraically.
Fig.2.9
Applying these superimposed voltage figures to the circuit; the end result looks something like
this:
Fig.2.10
RESULT:
14

The voltage across R2 is 8 volt is proved by thevenin’s and super position theorems.

EXPERIMENT # 7
OBJECT: Introduction of PSPICE Programming
THEORY:
Circuit components -
The first letter in each respective line primarily identifies all components in a PSPICE source file.
Characters following the identifying letter are used to distinguish one component of a certain type
from another of the same type (r1, r2, r3, rload, r pullup, etc.).
1.Passive components
RESISTORS
r1 1 0 2t (Resistor R1, 2t = 2 Tera-ohms = 2 TΩ)
r2 1 0 4g (Resistor R2, 4g = 4 Giga-ohms = 4 GΩ)
r3 1 0 47meg (Resistor R3, 47meg = 47 Mega-ohms = 47 MΩ)
r4 1 0 3.3k (Resistor R4, 3.3k = 3.3 kilo-ohms = 3.3 kΩ)
r5 1 0 55m (Resistor R5, 55m = 55 milli-ohms = 55 mΩ)
r6 1 0 10u (Resistor R6, 10u = 10 micro-ohms 10 µΩ)
r7 1 0 30n (Resistor R7, 30n = 30 nano-ohms = 30 nΩ)
r8 1 0 5p (Resistor R8, 5p = 5 pico-ohms = 5 pΩ)
r9 1 0 250f (Resistor R9, 250f = 250 femto-ohms = 250 fΩ)
Scientific notation:
r10 1 0 4.7e3 (Resistor R10, 4.7e3 = 4.7 x 103
ohms = 4.7 kilo-ohms = 4.7 kΩ)
r11 1 0 1e-12 (Resistor R11, 1e-12 = 1 x 10-12
ohms = 1 pico-ohm = 1 pΩ)
28

CAPACITORS
General form: c[name] [node1] [node2] [value] ic=[initial voltage]
Example 1: c1 12 33 10u
Example 2: c1 12 33 10u ic=3.5
Comments: The "initial condition" (ic=) variable is the capacitor's voltage in units of volts at the
start of DC analysis. It is an optional value, with the starting voltage assumed to be zero if
unspecified. Starting current values for capacitors are interpreted by SPICE only if the .tran
analysis option is invoked (with the "uic" option).
INDUCTORS
General form: l[name] [node1] [node2] [value] ic=[initial current]
Example 1: l1 12 33 133m
Example 2: l1 12 33 133m ic=12.7m
Comments: The "initial condition" (ic=) variable is the inductor's current in units of amps at the
start of DC analysis. It is an optional value, with the starting current assumed to be zero if
unspecified. Starting current values for inductors are interpreted by SPICE only if the .tran
analysis option is invoked.
INDUCTOR COUPLING (transformers)
General form: k[name] l[name] l[name] [coupling factor]
Example 1: k1 l1 l2 0.999
Comments: SPICE will only allow coupling factor values between 0 and 1 (non-inclusive), with 0
representing no coupling and 1 representing perfect coupling. The order of specifying coupled
inductors (l1, l2 or l2, l1) is irrelevant.
2. Sources
AC SINEWAVE VOLTAGE SOURCES (when using .ac card to specify frequency):
General form: v[name] [+node] [-node] ac [voltage] [phase] sin
Example 1: v1 1 0 ac 12 sin
Example 2: v1 1 0 ac 12 240 sin (12 V 240∠ o
)
Comments: This method of specifying AC voltage sources works well if you're using multiple
sources at different phase angles from each other, but all at the same frequency. If you need to
specify sources at different frequencies in the same circuit, you must use the next method!
AC SINEWAVE VOLTAGE SOURCES (when NOT using .ac card to specify frequency):
General form: v[name] [+node] [-node] sin([offset] [voltage]
+ [freq] [delay] [damping factor])
Example 1: v1 1 0 sin(0 12 60 0 0)
Parameter definitions:
offset = DC bias voltage, offsetting the AC waveform by a specified voltage.
voltage = peak, or crest, AC voltage value for the waveform.
freq = frequency in Hertz.
delay = time delay, or phase offset for the waveform, in seconds.
damping factor = a figure used to create waveforms of decaying amplitude.
Comments: This method of specifying AC voltage sources works well if you're using multiple
sources at different frequencies from each other. Representing phase shift is tricky, though,
necessitating the use of the delay factor.
DC VOLTAGE SOURCES (when using .dc card to specify voltage):
General form: v[name] [+node] [-node] dc
Example 1: v1 1 0 dc
29

Comments: If you wish to have SPICE output voltages not in reference to node 0, you must use
the .dc analysis option, and to use this option you must specify at least one of your DC sources in
this manner.
DC VOLTAGE SOURCES (when NOT using .dc card to specify voltage):
General form: v[name] [+node] [-node] dc [voltage]
Example 1: v1 1 0 dc 12
Comments: Nothing noteworthy here!
PULSE VOLTAGE SOURCES
General form: v[name] [+node] [-node] pulse ([i] [p] [td] [tr]
+ [tf] [pw] [pd])
i = initial value
p = pulse value
td = delay time (all time parameters in units of seconds)
tr = rise time
tf = fall time
pw = pulse width
pd = period
Example 1: v1 1 0 pulse (-3 3 0 0 0 10m 20m)
Comments: Example 1 is a perfect square wave oscillating between -3 and +3 volts, with zero rise
and fall times, a 20 millisecond period, and a 50 percent duty cycle (+3 volts for 10 ms, then -3
volts for 10 ms).
AC SINEWAVE CURRENT SOURCES (when using .ac card to specify frequency):
General form: i[name] [+node] [-node] ac [current] [phase] sin
Example 1: i1 1 0 ac 3 sin (3 amps)
Example 2: i1 1 0 ac 1m 240 sin (1 mA 240∠ o
)
Comments: The same comments apply here (and in the next example) as for AC voltage sources.
AC SINEWAVE CURRENT SOURCES (when NOT using .ac card to specify frequency):
General form: i[name] [+node] [-node] sin([offset]
+ [current] [freq] 0 0)
Example 1: i1 1 0 sin(0 1.5 60 0 0)
DC CURRENT SOURCES (when using .dc card to specify current):
General form: i[name] [+node] [-node] dc
Example 1: i1 1 0 dc
DC CURRENT SOURCES (when NOT using .dc card to specify current):
General form: i[name] [+node] [-node] dc [current]
Example 1: i1 1 0 dc 12
Comments: Even though the books all say that the first node given for the DC current source is
the positive node, that's not what I've found to be in practice. In actuality, a DC current source in
SPICE pushes current in the same direction as a voltage source (battery) would with its negative
node specified first.
PULSE CURRENT SOURCES
General form: i[name] [+node] [-node] pulse ([i] [p] [td] [tr]
+ [tf] [pw] [pd])
i = initial value
30

p = pulse value
td = delay time
tr = rise time
tf = fall time
pw = pulse width
pd = period
Example 1: i1 1 0 pulse (-3m 3m 0 0 0 17m 34m)
Comments: Example 1 is a perfect square wave oscillating between -3 mA and +3 mA, with zero
rise and fall times, a 34 millisecond period, and a 50 percent duty cycle (+3 mA for 17 ms, then -3
mA for 17 ms).
VOLTAGE SOURCES (dependent):
General form: e[name] [out+node] [out-node] [in+node] [in-node]
+ [gain]
Example 1: e1 2 0 1 2 999k
Comments: Dependent voltage sources are great to use for simulating operational amplifiers.
Example 1 shows how such a source would be configured for use as a voltage follower, inverting
input connected to output (node 2) for negative feedback, and the noninverting input coming in on
node 1. The gain has been set to an arbitrarily high value of 999,000. One word of caution, though:
SPICE does not recognize the input of a dependent source as being a load, so a voltage source tied
only to the input of an independent voltage source will be interpreted as "open." See op-amp
circuit examples for more details on this.
Analysis options-
AC ANALYSIS:
General form: .ac [curve] [points] [start] [final]
Example 1: .ac lin 1 1000 1000
Comments: The [curve] field can be "lin" (linear), "dec" (decade), or "oct" (octave), specifying
the (non)linearity of the frequency sweep. specifies how many points within the frequency sweep
to perform analyses at (for decade sweep, the number of points per decade; for octave, the number
of points per octave). The [start] and [final] fields specify the starting and ending frequencies of
the sweep, respectively. One final note: the "start" value cannot be zero!
DC ANALYSIS:
General form: .dc [source] [start] [final] [increment]
Example 1: .dc vin 1.5 15 0.5
Comments: The .dc card is necessary if you want to print or plot any voltage between two
nonzero nodes. Otherwise, the default "small-signal" analysis only prints out the voltage between
each nonzero node and node zero.
TRANSIENT ANALYSIS:
General form: .tran [increment] [stop_time] [start_time]
+ [comp_interval]
Example 1: .tran 1m 50m uic
Example 2: .tran .5m 32m 0 .01m
Comments: Example 1 has an increment time of 1 millisecond and a stop time of 50 milliseconds
(when only two parameters are specified, they are increment time and stop time, respectively).
Example 2 has an increment time of 0.5 milliseconds, a stop time of 32 milliseconds, a start time
of 0 milliseconds (no delay on start), and a computation interval of 0.01 milliseconds.
Default value for start time is zero. Transient analysis always beings at time zero, but storage of
data only takes place between start time and stop time. Data output interval is increment time, or
(stop time - start time)/50, which ever is smallest. However, the computing interval variable can be
used to force a computational interval smaller than either. For large total interval counts, the itl5
31

variable in the .options card may be set to a higher number. The "uic" option tells SPICE to "use
initial conditions."
PLOT OUTPUT -
General form: .plot [type] [output1] [output2] . . . [output n]
Example 1: .plot dc v(1,2) i(v2)
Example 2: .plot ac v(3,4) vp(3,4) i(v1) ip(v1)
Example 3: .plot tran v(4,5) i(v2)
Comments: SPICE can't handle more than eight data point requests on a single .plot or .print card.
If requesting more than eight data points, use multiple cards!
Also, here's a major caveat when using SPICE version 3: if you're performing AC analysis and you
ask SPICE to plot an AC voltage as in example #2, the v(3,4) command will only output the real
component of a rectangular-form complex number! SPICE version 2 outputs the polar magnitude
of a complex number: a much more meaningful quantity if only a single quantity is asked for. To
coerce SPICE3 to give you polar magnitude, you will have to re-write the .print or .plot argument
as such: vm(3,4).
PRINT OUTPUT-
General form: .print [type] [output1] [output2] . . . [output n]
Example 1: .print dc v(1,2) i(v2)
Example 2: .print ac v(2,4) i(vinput) vp(2,3)
Example 3: .print tran v(4,5) i(v2)
Comments: SPICE can't handle more than eight data point requests on a single .plot or .print card.
If requesting more than eight data points, use multiple cards!
FOURIER ANALYSIS -
General form: .four [freq] [output1] [output2] . . . [output n]
Example 1: .four 60 v(1,2)
Comments: The .four card relies on the .tran card being present somewhere in the deck, with the
proper time periods for analysis of adequate cycles. Also, SPICE may "crash" if a .plot analysis
isn't done along with the .four analysis, even if all .tran parameters are technically correct. Finally,
the .four analysis option only works when the frequency of the AC source is specified in that
source's card line, and not in an .ac analysis option line.
It helps to include a computation interval variable in the .tran card for better analysis precision. A
Fourier analysis of the voltage or current specified is performed up to the 9th harmonic, with the
[freq] specification being the fundamental, or starting frequency of the analysis spectrum.

EXPERIMENT # 11
OBJECT: WRITE A PSPICE PROGRAM FOR AC-ANALYZE OF IMPEDANCE
NETWORKS TO DETERMINE THE MAGNITUDE & PHASE OF NODE
VOLTAGES, COMPONENTS VOLTAGES AND COMPONENT CURRENTS.
THEORY:
11.1 Simple AC resistor-capacitor circuit
Fig. 11.1 Series RC Circuit
The .ac card specifies the points of ac analysis from 60Hz to 60Hz, at a single point. This card, of
course, is a bit more useful for multi-frequency analysis, where a range of frequencies can be
analyzed in steps. The .print card outputs the AC voltage between nodes 1 and 2, and the AC
voltage between node 2 and ground.

11.2 Multiple-Source AC network
One of the idiosyncrasies of SPICE is its inability to handle any loop in a circuit exclusively
composed of series voltage sources and inductors. Therefore, the "loop" of V1-L1-L2-V2-V1 is
unacceptable. To get around this, I had to insert a low-resistance resistor somewhere in that loop
to break it up. Thus, we have Rbogus between 3 and 4 (with 1 pico-ohm of resistance), and V2
between 4 and 0. The circuit above is the original design, while the circuit below has Rbogus inserted
to avoid the SPICE error.

EXPERIMENT # 13
OBJECT: WRITE A PSPICE PROGRAM FOR AC-ANALYZE OF IMPEDANCE
NETWORKS TO DETERMINE THE MAGNITUDE,PHASE,REAL &
IMAGINARY PART OF NODE VOLTAGES, COMPONENTS VOLTAGES AND
COMPONENT CURRENTS.
THEORY:
11.1 Simple AC resistor-capacitor circuit
Fig. 11.1 Series RC Circuit
The .ac card specifies the points of ac analysis from 60Hz to 60Hz, at a single point. This card, of
course, is a bit more useful for multi-frequency analysis, where a range of frequencies can be
analyzed in steps. The .print card outputs the AC voltage between nodes 1 and 2, and the AC
voltage between node 2 and ground.
