What are clipper and clamper circuits
Short answer
A clipper removes portions of a waveform above or below a reference level, altering its shape, using diodes and resistors. A clamper shifts the entire waveform by adding a DC level without changing its shape, using a capacitor, diode, and resistor.
What is clipper and clamper circuit?
- Clipper: a circuit that removes (clips) the portion of an input waveform lying above or below a chosen reference level, without altering the rest of the waveform. It uses diodes and resistors (and a battery for the reference level). Example: a diode and resistor that cut the positive peaks of a sine wave.
- Clamper: a circuit that shifts the entire input waveform up or down by adding a dc level, without changing its shape (peak-to-peak value stays the same). It uses a capacitor, a diode and a resistor (and a battery for extra shift). Also called a dc restorer or level shifter. Example: a sine wave of ±5 V shifted to a range of 0 V to +10 V.
| Clipper | Clamper | |
|---|---|---|
| Effect | cuts part of the waveform | shifts the waveform |
| Shape | changed | unchanged |
| Capacitor | not needed | needed |
