Negative Clamper Circuit With Positive Bias. Biased positive clipper and biased negative clipper. Using this the circuit of the negative clamper with positive reference voltage is constructed as below.
Positive clamper with negative bias video lecture from rectifier and filters chapter of basic electronics for all branches of diploma. Positive clamper with negative bias if negative biasing is applied to the positive clamper then it is said to be a positive clamper with negative bias. The output waveform is clamped to 10v the value of the battery.
During the negative half cycle the battery voltage reverse biases the diode when the input supply voltage is less than the battery voltage.
First connect the transformer s 12v ac source pin to the capacitor and then connect diode s positive terminal to the other terminal of capacitor and negative terminal to 0v pin of the transformer. Since this is a negative clamper cathode to ground the top of the output wave touch the 10v reference line. A biased clipper comes in handy when a small portion of positive or negative half cycles of the signal voltage is to be removed. A negative clamper circuit if biased with some positive reference voltage that voltage will be added to the output to raise the clamped level.
