DIODE CLIPPERS

Clippers are networks that employ


diodes to “clip” away a portion of an
input signal without distorting the
remaining part of the applied waveform.
DIODE CLIPPERS

Determining vo for the diode in


the “on” state.
EXAMPLE: Determine the output waveform for the network.

Solution
EXAMPLE: Determine the output waveform for the network.

Solution
EXAMPLES:
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.
EXAMPLE:
Determine vo for the network shown.
Solution
EXAMPLE:
Determine vo for the network if Si
diode is used.
Solution

Determining vo for the diode in the


“on” state.
EXAMPLES:
CLAMPERS

A clamper is a network constructed of a diode, a


resistor, and a capacitor that shifts a waveform to
a different DC level.
CLAMPERS
R is chosen such that the discharge
period 5τ=5RC is much larger than the
period T/2→T, and the capacitor is
assumed to hold onto all its charge.

Diode “on” and the capacitor Determining vo with the diode


charging to V volts. “off.”
CLAMPERS
EXAMPLE

Determine vo for
the network.

Solution

Determining vo and VC with the diode in the “on” state. Determining vo with the diode in the “off” state.
EXAMPLE
CLAMPER CIRCUITS

Clamping circuits with ideal diodes (5τ = 5RC >> T/2).
