brief introduction: Introduction:The junction gate field-effect transistor (JFET or JUGFET) is the simplest type of field-effect transistor. They are three-terminal semiconductor devices that can be used as electronically-controlled switches, amplifiers, or voltage-controlled resistors. A junction gate field effect transistor utilizes a diode-like structure between the gate and the drain to source channel. It is a simple field effect transistor, which is doped with an n or p-type doping agent. On one side of the tr
