A circuit which removes the peak of a waveform is known as a clipper.

Clipper: clips negative peak at -0.7 V.
During the positive half cycle of the 5 V peak input, the diode is reversed biased. The diode does not conduct. It is as if the diode were not there. The positive half cycle is unchanged at the output V(2) in Figure below. Since the output positive peaks actually overlays the input sinewave V(1), the input has been shifted upward in the plot for clarity. In Nutmeg, the SPICE display module, the command “plot v(1)+1)” accomplishes this.

• REVIEW
• A resistor and diode driven by an AC voltage source clips the signal observed across the diode.
• A pair of anti-parallel Si diodes clip symmetrically at ±0.7V
• The grounded end of a clipper diode(s) can be disconnected and wired to a DC voltage to clip at an arbitrary level.
• A clipper can serve as a protective measure, preventing a signal from exceeding the clip limits.
