CLIPPERS AND CLAMPERS IN ELECTRONICS PDF

In electronics, a clipper is a circuit designed to prevent the output from exceeding a . A clamper circuit is not a clipper, but the simple diode version has a similar topology to a clipper with the exception that the resistor is replaced with a. Complete tutorial about different types and applications of clipper circuits in series and parallel; positive and negative clamper circuits, etc. A clipper circuit chops of output voltage beyond the requirement while clamper clamps the output to a definite voltage level, actually adds/subtracts a DC level.

Clippers may be classified based on the orientation of the diode. When the input supply voltage V i becomes greater than the battery voltage V Bthe diode D is electrobics biased. During positive half cycle: When the input supply voltage V i becomes greater than the battery voltage V Bthe diode is forward biased by the input supply voltage V i. Shunt negative clipper with bias Shunt negative clipper with positive bias During the positive half cycle, the diode is reverse biased by the input supply voltage V i and forward biased by the battery voltage V B.

The vertical line in the diode symbol represents the cathode n-side and the opposite end represents the anode p-side. The clipper circuits are generally categorized into three types: If the diode is arranged in such a way that the arrowhead of the diode points towards the input and the diode is in series with the output load resistance, ajd the clipper is said to be a series positive clipper.

So the negative half cycle is completely blocked or removed at the output.

Therefore, the diode is forward biased by the battery voltage V B. Initially, the input supply voltage is less than the battery voltage. Therefore, the diode D is reverse biased during the negative half cycle.

Clippers may be classified into two types based on the positioning of the diode. When the input supply voltage V i becomes greater than the battery voltage V Bthe diode will become reverse biased. As shown in the figure, the positive terminal of the battery is connected to n-side and the negative terminal of the battery is connected to p-side of the diode.

Unsourced material may be challenged and removed. Therefore, during the negative half cycle, no signal appears at the output.

That means the diode is forward biased by input supply voltage V i and reverse biased by battery voltage V B. During the positive half cycle, the diode is reverse biased by the input supply voltage V i and forward biased by the battery voltage V B.

So no signal appears at the output during the positive half cycle. The various types of clippers are as follows: The resistor is mainly used to limit the current flowing through the diode when it is forward biased. This page was last edited on 26 Septemberat In series negative clipper, the negative half cycles of the input AC signal is removed at the output.

In shunt positive clipper, during the positive half cycle the diode is forward biased and hence no output is generated. The only difference is an extra element called battery is used anx series positive clipper with bias. Shunt negative clipper with negative bias During the positive half cycle, the diode is reverse biased by both input supply voltage V i and battery voltage V B. For very small values of clipping voltage on low-level signals the I-V curve of the diode can result in clipping onset that is not very sharp.

Therefore, the diode is reverse biased by the input supply voltage V i. Used in TV transmitters and Receivers They are employed for different wave generation such as square, rectangular, or trapezoidal waves. That means the diode D is forward biased due clammpers the ahd supply voltage.

Therefore, the diode D 1 and diode D 2 are reverse biased by the battery voltage. However, we are also supplying the voltage from another source called battery. That means the negative terminal A is connected to n-side and the positive terminal B is connected to p-side of the diode.

The construction of the series negative clipper with bias is almost similar to the series negative clipper. Thus, the clipping removal of a signal takes place during the positive half cycle only when the input supply voltage becomes greater than the battery voltage. Let us consider a dual clipper circuit in which a sinusoidal ac voltage is applied to the input terminals of the circuit.

The series kn passes the input signal to the output load when the diode is dlampers biased and blocks the input signal when the diode is reverse biased. Therefore, the diode D is forward biased during the negative half cycle.

Shunt positive clipper In shunt clipper, the diode is connected in parallel with the output load resistance. As shown in the figure, the positive terminal of the battery is connected to p-side and the negative terminal of the battery is connected to n-side of the diode.
