FET Switch: A Voltage-Controlled Analog Switch

This is a JFET switch circuit.This circuit uses a MPF102 JFET transistor. In this circuit, the JFET is symmetrical, so the input can be source or drain. The MPF102 is used because this transistor has gate’s reverse breakdown voltage of greater than 25 and in order DSG. The supply of this circuit is ±12V since the maximum gate’s reverse breakdown […]
