Current flows into the Drain (D), through the channel, and out of the Source (S) In the normal operation of an n-channel device, the Drain (D) is positive with respect to the Source (S).Major structure is n-type material (channel) between embedded p-type materialto form 2 p-n junction.FET is unipolar – uses only one type of current carrier.


BJT is bipolar – conduction both hole and electron.Can be fabricated with fewer processing.High input impedance (M)(Linear AC amplifier system).What is the difference between JFET and MOSFET?.JFET (junction field-effect transistor).MOSFET (metal-oxide-semiconductor field-effect transistor).Also used as amplifier and logic switches.Field-effect transistor (FET) are important devices such as BJTs.CHAPTER 4 :JFET Junction Field Effect Transistor
