Clamper circuit:

  • A clamper is an electronic circuit that changes the DC level of a signal to the desired level without changing the shape of the applied signal.
  • The Clamper circuit moves the whole signal up or down to set either the positive feedback or negative feedback of the signal at the desired level.
  • It consists of capacitors and diodes to shift the voltage level.

 

In a Voltage doubler circuit, the output voltage is double the input voltage with the circuit diagram as shown:

554F2 R.D Madhu 22.10.19 D 11

Important Points

  • Clipper circuits are used to remove the part of a signal above or below some defined reference level.
  • One example of a clipper circuit is a half-wave rectifier that clips off the negative-going waveform.
