The junction-gate field-effect transistor (JFET) is one of the simplest types of field-effect transistor. ... Unlike bipolar junction transistors, JFETs are exclusively voltage-controlled in that they do not need a biasing current. Electric charge flows through a semiconducting channel between source and drain terminals.

6. JFET.
• IT IS A VOLTAGE CONTROL SEMICONDUCTOR DEVICE
• IN THIS, THE CURRENT IS CARRIED BY ONLY ONE TYPE OF CARRIER . SO, IT IS
UNIPOLAR DEVICE ( ONE POLARITY OF CHARGE CARRIERS)
• NO MINORITY CARRIER STORAGE
