Diode Clippers
•
The diode in a series clipper “clips”
any voltage that does not forward
bias it:
•A reverse-biasing polarity
•A forward-biasing polarity less than
0.7 V (for a silicon diode)
2Prepared By S ARUN M.Tech Clipper and Clamper
Biased Clippers
Adding a DC source in
series with the clipping
diode changes the
effective forward bias of
the diode.
3Prepared By S ARUN M.Tech Clipper and Clamper
Parallel Clippers
The diode in a parallel clipper
circuit “clips” any voltage that
forward bias it.
DC biasing can be added in
series with the diode to change
the clipping level.

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

Biased Clamper Circuits
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.
