CLIPPERS

Clippers:

 Clipping circuits are used to select that portion of the input wave which lies above or below some reference level. Some of the clipper circuits are discussed here. The transfer characteristic (v_o vs v_i) and the output voltage waveform for a given input voltage are also discussed.

Clipper Circuit 1:

The circuit shown in fig. 1, clips the input signal above a reference voltage (VR). In this clipper circuit,           If vi < VR, diode is reversed biased and does not conduct. Therefore, vo = vi and,   if vi > VR, diode is forward biased and thus,                                              vo=VR.
