Definition and working principle of junction FET

Junction Field-Effect Transistor (JFET)JFET isto make two highly doped P-regions on the same N-shaped semiconductor, and connect them together, the resulting electrode is called gate g, and the N-type semiconductor leads to two electrodes at both ends, respectively, called drain d. Source s. Junction FET is a kind of amplifying three-terminal active device, is the simplest kind of unipolar FET, it can be divided into n-channel or P-channel two. Its working principle is to control the output current by changing the conductivity of the channel by voltage.
