Junction Field Effect Transistor
A Junction Field Effect Transistor (JFET) serves as a distinct transistor type, mainly employed for amplifying low-power signals. The operation of JFETs involves regulating the current between the source and drain terminals through the influence of an electric field. The voltage applied to the gate terminal regulates the conducting channel width, controlling the current flow. Commonly used in audio preamplifiers and oscillators, JFETs offer high input impedance and its various applications are in signal amplification scenarios.
There are two types of JFET namely N-channel JFET and P-Channel JFET. The symbol for these two types are shown below:
Types of Transistors
Transistor is similar to a semiconductor device which when used either conducts or insulates electric current or voltage. Prepared by three American physicists, John Bardeen, Walter Brattain, and William Shockley in the year 1947. There are different types of transistors based on their working principle.
This article deals with various types of transistor in detail along with introduction of transistor, its working and applications
