Abstract

Two types of field-effect transistor exist, the junction gate field-effect transistor and the metal-oxide field-effect transistor. The abbreviation FET is commonly used to refer to either type while terms JFET (sometimes JUGFET) and MOSFET conveniently serve to distinguish the two variants. Compared with the bipolar transistor, both types of FET exhibit very high input resistance which leads to very high current and power gain. In this chapter the topic of FETs is broached by discussing the JFET. After dealing with both JFETs and MOSFETs and a cross-section of their circuit applications, a brief treatment of thermionic valves is included since amplifying types possess very similar properties to FETs.
