WebThe depletion MOSFET circuit, however, has much higher input impedance than a similar JFET configuration. While a BJT device controls a large output (collector) current by means of a relatively small input (base) current, the FET device controls an output (drain) current by means of a small input (gate-voltage) voltage. Webmeans of a relatively small base current. It is a current controlled device. 1.FET controls drain current by means of small gate voltage. It is a voltage controlled device 2.Has …
