Can JFET be an amplifier?
Can JFET be an amplifier? JFET Amplifier Current and Power Gains Because of this common source JFET amplifiers are extremely valuable as impedance matching circuits or are used as voltage amplifiers. How does JFET acts as an amplifier? Using JFET as an amplifier The weak signal applied at its input circuit causes a large change in its output circuit. The load resistor is used to reflect this large change which causes the large voltage drop across the load resistor, and thus, a large current is received at the output terminal.
