NEGATIVE SHUNT CLIPPER • The negative clipper has
allowed to pass the positive half cycle of the input voltage and clipped the negative half cycle completely.
• In such a circuit the diode acts as a closed switch for a negative input voltage (i.e. v < o) and as an open switch for a positive input voltage (i.e. v o) the output waveform of the circuit is the same as that of series negative clipper.

NEGATIVE SHUNT CLIPPER WITH BIAS
• In negative shunt biased circuit clipping take place during the negative half cycle only when the input voltage (v < v ).• The clipping level can be shifted up or down by varying
the bias voltage (—v ). it will be interesting to know that if the polarity of the bias voltage is reversed.• Then the resulting circuits will be as shown in the entire
signal below the voltage level vii has been clipped off in the diagram shown in next slide.

CONCLUSIONIN THE NEGATIVE HALF CYCLE OF THE SIGNAL VOLTAGE IS APPLIED AT THAT TIME DIODE IS IN REVERSE BIASED CONDITION.SO WE CAN OBSERVE THAT DIODE ACTS AS OPEN SWITCH AND THERE IS ZERO VOLTAGE APPEAR ACROSS RL.
