A junction field effect transistor jfet is a simple fet with a pn junction in which output current is controlled by an input voltage. It has some important characteristics notably a very high input resistance. The transfer characteristic for a jfet can be determined experimentally keeping drain source voltage vds constant and determining drain current id for various values of gate source voltage vgs.
The most important characteristics of the jfet are as follows.
The most important characteristics of the jfet are as follows. There are two basic types of field effect transistors. The n channel jfet consists of p type material in n type substrate whereas n type materials are used in the p type substrate to form a p channel jfet. The gate is a control element while the drain and source provide the same function as the emitter and collector on a bipolar junction transistor.
