field-effect transistor

Field-Effect Transistor typically used as an impedance converter at the element in a condenser microphone. A MOSFET is a particular kind of FET, which is finding itself used more and more in power amplifiers. (See MOSFET)

The MOSFET is a particular type of Field-Effect Transistor (FET) where the output current flowing between the source and drain terminals is controlled by a variable electric field applied to the gate terminal. The gate design determines the type of FET. In the MOSFET, the gate is insulated...
