The document discusses two configurations of operational amplifiers (OP-AMPs): inverting and non-inverting. The inverting configuration uses a single resistor connected to the input and a feedback resistor, producing a 180 degree phase shift between input and output. The non-inverting configuration uses a resistor connected to ground and a feedback resistor, with the input directly applied to the non-inverting terminal and the output in phase with the input. Circuit diagrams, input/output waveforms, and voltage gain calculations are provided for both configurations.

3. INVERTING OP-AMP CONFIGURATION
This is a diagram of an INVERTING OP-AMP.
This circuit makes use of an OP-AMP, a single
resistor(R1) connected to input and a feedback resistor
(R2) connected to R1.
The Inverting Amplifier produces a 180˚ phase shift
in voltage from input to output.

4. INPUT AND OUTPUT WAVEFORMS OF AN
INVERTING OP-AMP
(gain assumed to be 2)
 The input and output signals of the inverting amplifier
are not in-phase with each other.

5. NON INVERTING OP-AMP CONFIGURATION
 This is a diagram of NON-INVERTING OP-AMP.
 This circuit consists of an OP-AMP, a single resistor
(R1) connected to ground and feedback resistor (R2)
connected to R1.
 Input Voltage is directly applied through the noninverting terminal.

6. NON INVERTING OP-AMP CONFIGURATION
 R1 and R2 form a simple potential divider network
across the non-inverting amplifier with the voltage gain
of the circuit being determined by the ratios
of R2 and R1

7. INPUT AND OUTPUT WAVEFORMS OF AN NON
INVERTING OP-AMPINVERTING OP-AMP
 The input voltage signal, ( Vin ) is applied directly to the
non-inverting ( + ) input terminal which means that the
output gain of the amplifier becomes "Positive".
 The result of this is that the output signal is "in-phase"
with the input signal.
