Amazing facts about clipper circuit which scores you high


  1. In today’s article, we are going to study about ‘ Amazing facts about clipper circuit which scores you high’ How beneficial it is and what is the clipper circuit. We will also read about some more topics like positive clipper, negative clipper, biased clipper, combinational clipping, application of clipper etc in Detail.  So, take your notebooks in you hand and get ready to study physics in an easy and sorted way.

Clipper circuit

The circuit with which the wave form is shaped by removing a portion of the applied wave is known as clipping circuit. That means clipper circuit is a type of circuit which is used to reshape the waveform.

Use of clipper circuit

Clipper circuit have a wide application in Radar, digital and other electronic circuit. There are so many clipper present in market, but will discuss here only Diode clipper. These clipper can remove signal voltage above or below a specified level.

Types of clipper

Here we explain four types of clipper that is,

  1. Positive clipper
  2. Negative clipper
  3. Biased clipper
  4. Combinational clipper

1) Positive clipper

A positive clipper is that clipper which removes the positive half cycle of the input voltage.

Clipper circuit

Working of positive clipper

Here we connect a diode to the input AC source voltage and also connect a output load RL parallel to the diode. When we give the positive half cycle of AC voltage in input then Diode becomes in forward bias. And it will conducts or acts like a ‘ON’ circuit. Therefore all voltage comes back and we get zero voltage at load resistance RL. At that time there is no positive voltage coming out. And that’s why we called it a positive clipping.

When we give negative cycle of AC voltage then Diode becomes reverse bias. Or we can say that it acts like a ‘OFF’ circuit. So all voltage we get at load RL and we get negative cycle on the output. So this is the circuit of positive clipper.

Output voltage Vo = -(RL/ R+RL). Vm

Where Vm is the maximum input voltage.

2) Negative clipping

When we give positive Cycle in the input at that time diode is in reverse bias so it acts like a switch OFF circuit therefore we get the positive output cycle at the load resistance RL. Now if we give negative cycle then Diode comes in forward bias. And acts like a switch ‘ON’ circuit and all negative voltage comes back. And we get no (output) at RL. So that’s why there is a negative cycle clip and we can say that these type of circuit is called negative clipper.

(3) Bias clipping

Bias clipping is further classified into two parts that is,

  1. Positive bias clipping
  2. Negative bias clipping

Positive bias clipping

Here, we explain the positive bias clipper in which only some small portion of positive cycle clipped. Here in the fig, we have connected a diode and a small battery. Both are connected in series. And also they are parallel with the load resistance RL. when we give the positive Cycle then diode comes in forward bias so, it will heavily conducts but at the same time battery which is connected in series gives some reverse voltage to the Diode. At that time due to the difference between these voltage gets us some output. And in this way a small portion of positive cycle will be clipped. And this is called positive bias clipping.

Negative bias clipping

In negative bias clipping we connect the diode and battery in series as shown in fig. And a ‘RL’ load connected in parallel. When we give the negative cycle then Diode becomes forward biased. And a battery which is connected in series makes the diode reverse bias. At this time portion of negative cycle clipped, this is called negative bias clipping.

4) Combinational clipping

In combinational clipping we connect the Diode D1 and D2 and both having battery V1 and V2 connected in series. And all these are connected with RL, which is parallel in circuit. Here we give a full AC cycle in the input in such a way that D1 and V1 clip the some portion of positive cycle. And D2 and V2 clip the some portion of negative cycle. In this way we get the output as shown in fig. In which both positive and negative cycle are clipped. So many times we use the combinational clipping for getting the square waves.

Application of clipper

  1. Changing the shape of waveform- clippers are used to change the shape of waveform. For example clipper can be used to convert sine wave into square wave, by changing there shape.
  2. Circuit transient protection- clipper can low down the high voltage into the small value voltage. So that’s why it protects the damage of home appliances like freeze, t.v., microwave etc.


So our article is finished and after completely reading this article, one can easily tell what a clipper circuit. And how we can explain it.

‌So one can say that they got a detailed information about clipping, types of clipper circuit, positive clipping, negative clipping, combinational clipping, bias clipping, application of clipper etc.
