Noise in Amplifiers and its Types: Noise in Amplifiers - Noise is any kind of unwanted signal that is not related to the input. Any electronic component produces a certain…
What is Single Stage Transistor Amplifier? - Circuit Diagram and its Workings When only one transistor with associated circuit is used for increasing the strength of a weak signal, the…
Complementary Metal Oxide Semiconductor (CMOS): With active load switching, the current drain with a low output is approximately equal to ID(sat). This may cause a problem with battery operated equipment.…
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…
FET as a Voltage Variable Resistor (VVR): FET is a device that is usually operated in the constant-current portion of its output characteristics. But if it is operated in the…
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…
Common Source JFET Amplifier with AC Equivalent Circuit: The Common Source JFET Amplifier Circuit configuration is the most widely employed configuration. It is because this configuration provides high input impedance,…
