Junction Field Effect Transistor (JFET) is a type of transistor that produces two highly doped P-regions on the same N-shaped semiconductor and connects them together. The resulting electrodes are called gate g, and the N-shaped semiconductor has two electrodes at each end, called drain d and source s. Junction field-effect transistor is a three terminal active device with amplification function, which is the simplest type of unipolar field-effect transistor. It can be divided into two types: N-channel or P-channel
Function of testing report:
