Assignment 4 (Spring 2012)
(Solution)
Circuit Theory (PHY301)
Marks: 15
Q.1:
In the given clamper circuit shown below, find VO and output wave shape for given
input signal. (Assuming diode to be used of silicon)
Solution:
Assuming waves time period=50us
The Input voltage (Vin) changes from 0 to +5v at t=0 and remain at +5V.
Since diode cannot conduct during this interval and C cannot so no any action takes
place.
During negative half cycle of the input wave the circuit will be like this.

Assignment 4 (Spring 2012)

(Solution)

Circuit Theory (PHY301) Marks: 15

Q.1:

In the given clamper circuit shown below, find VO and output wave shape for given input signal. (Assuming diode to be used of silicon)

Solution: Assuming waves time period=50us The Input voltage (Vin) changes from 0 to +5v at t=0 and remain at +5V. Since diode cannot conduct during this interval and C cannot so no any action takes place.

During negative half cycle of the input wave the circuit will be like this.

so by kvl in circuit

10 3 0.

By this it is clear that 12.3v has been added to

Vin and Vo will shift by same amount

The circuit will be open

Vb v v

Vc vin Vb Vd Vc Vc v

For positive signal

KVL across the outer loop 0 5 12.3 0

Vi Vo Vc Vo Vo V

The Output wave shape will be like this
