Multivibrator definition and Types (Astable, Monostable and Bistable): A multivibrator is basically a two stage R-C coupled amplifier with positive feedback from the output of one amplifier to the input…
Power BJT - Construction, Operation and its Characteristics: Power transistors are large-area devices. Because of differences in geometry and doping concentrations, their properties tend to vary from those of the…
Radio Communication System - Block Diagram and types: Radio communication is very popular technique of communicating a message. The radio waves are electromagnetic waves produced due to escape of electrical…
Emitter Follower Circuit - Operation, Advantages and Applications: Emitter Follower Circuit is also a negative current feedback circuit. This circuits exhibits a large input impedance, a small output impedance, and…
Effect of Internal Transistor Capacitance: As we know already that at high frequencies, the coupling and bypass capacitors act as short circuit due to their low reactance and hence the…
Enhancement Type MOSFET - Construction, Operation and Characteristics: Although DE-MOSFET is useful in special applications, it does not enjoy widespread use. However, it played an important role in history because…
Depletion Type MOSFET - Construction, Operation and Characteristics: As we know already that when the gate is biased negative w.r.t. the source in an N-channel JFET, the depletion-region widths are…
Applications of FETs (Field Effect Transistors): Applications of FETs - FET has a very high input impedance (100 MΩ in case of JFETs and 104 to 109 MΩ in case of…
