Exercise Diode Clippers and Clampers
Adding a DC source in series with the clipping diode changes the effective forward
bias of the diode.

Clampers
A diode and capacitor can be combined to “clamp” an AC signal to a specific DC level.
Exercise Diode Clippers and Clampers
4
The input signal can be any type of waveform such as sine, square, and triangle waves.
The DC source lets you adjust the DC camping level.

Determine the output waveform for the network of Fig. 2.74.
Solution
diode on positive region aiding effect of V= 5 V.
vo =vi +5 V. Substituting id = 0 at vd= 0 Fig. 2.76 and vi = -5 V.
