This document discusses different types of clipper circuits. It defines clipper circuits as circuits used to remove parts of a signal that are above or below a defined reference level. There are two main types of clipper circuits: unbiased and biased. Unbiased clippers include positive and negative clippers, which clip either the positive or negative portions of a signal respectively. Biased clippers add an external bias voltage to adjust the clipping level, and also include positive and negative varieties.

3. What are clipper circuits?
Clippers Circuits are used to remove the part of a
signal that is above or below some defined reference level.
One of the simple example of a clipper is the half-wave
rectifier that circuit basically cut off everything at the
reference level of zero and let only the positive-going
(or negative-going) portion of the input waveform through.
Clipping circuits (also known as limiters, amplitude
selectors, orslicers)

5. Unbiased Positive Clippers
1. Positive clippers are used to clip positive portions of the input
signal and allow the negative portions of the signal to pass through
2. Figure below shows the input and output signal along with the
positive clipper. The positive cycle is completely clipped off by the
clipper.

6. Unbiased Negative Clippers
1. Negative clippers are used to clip negative portions of the input
signal and allow the positive portions of the signal to pass
through
2. Figure below shows the input and output signal along with the
negative clipper. The negative cycle is completely clipped off by
the clipper.

7. Biased Series Positive Clipper
As shown earlier, we saw that the clipping of the signal takes
place as soon as the input signal goes positive. If we want to
change/adjust the clipping level of AC voltage, then external
biasing voltage must be used. The figure given below shows a
biased (series) clipper.

8. Biased Series Negative Clipper
As shown earlier, we saw that the clipping of the signal takes
place as soon as the input signal goes negative. If we want to
change/adjust the clipping level of AC voltage, then external
biasing voltage must be used. The figure given below shows a
biased (series) clipper.
