Clampers

A diode and capacitor can be combined to “clamp” an AC signal to a specific DC level.

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.
