4. Problem statement
We have to analyze the behavior of semi-conductor
devices used in electronics devices i.e. in computer.
The most common semi-conductor device is transistor
and in turn the PN junction.
So our problem is to analyze the PN junction.
5. How to analyze PN junction
PN junction can be analyzed by constructing there
lumped circuit having with very simple circuit
components comprising of resistors and capacitors.
The lumped circuit can be named as “RC-model”.
Before going through the RC-model we will first throw
some light on resistor and capacitor separately.
6. Behavior of resistor
A resistor is an electrical element that introduce
hindrance to the flow of current.
From Ohm’s law, the equation of voltage across the
resistor is.
V1 - V0 IR
V IR

8. Behavior of capacitor
A capacitor is a circuit element that is use to store
electrical charge.
The equation of voltage across the capacitor is
d (V 1 V 0 )
C I
dt
dV
C I
dt
9. Behavior of PN junction
PN junction also resist the electrical current from
flowing and hence provide resistance.
It also stores charge across its junction as the
capacitors do hence behaving like capacitor.
10. Behavior of PN junction
The depletion layer of a PN junction is the interface of the
junction, and (as the name implies) is depleted of charge
carriers.
The bias voltage across the junction determines the
capacitance of the depletion layer.
11. RC-model
Considering the capacitive and resistive nature of a pn
junction we can represent it by an RC circuit.
V in Vc IR
and
C dV c I
dt
V in Vc RC dV c
dt
12. Ordinary Differential Equation
A differential equation is an algebraic equation that
contains some derivatives
e.g. dy
5 y 3x
dx
Derivative indicates a change in a dependent variable
with respect to an independent variable.
13. How to Solve ODEs
There are different methods to solve ordinary
differential equations.
Each method have its own advantage depending upon
the computation time and accuracy.
These methods trade off between computation time
and accuracy.
14. How to Solve ODEs
The methods are
1. Euler’s method.
2. Heun’s method.
3. Runge kutta’s 4th order method.
15. Euler’s Method.
Euler’s method is a numerical technique to solve
ordinary differential equations of the form
dy
f ( x , y ), y ( 0 ) y0
dx
Only first order ordinary differential equations can be
solved by using Euler’s method.
