Q. Draw and explain diode clipping circuit ?
A diode clipping circuit can be used to limit the voltage swing of a signal. Clipper circuits are used to clip a portion of the waveform. They are also known as amplitude limiters. The basic principle of clipping circuits is based on the unidirectional property of a diode.
During forward biased condition, diode acts like a close switch and during reverse biased condition; diode acts like an open switch. Clipping circuit may be classified as flows:
1. Positive clipping circuits.
2. Negative clipping circuits.
3. Biased clipping circuits.
4. Combinational or trapezoidal circuits.
The resistor is used in series with the source ton avoid the damage due to excessive current.
Q. Give an introductive notes about FET amplifier ? The small signal models for the common source FET can be used for analyzing the three basic FET amplifier configurations: (
