The 2N5457 field effect transistor can be used as a variable voltage resistor between the differential input terminals of the operational amplifier. In multiple decimal resistors, the parameter change of the resistance is linear with the voltage, which can provide good electronic gain control. The value of the resistance is determined by the operational amplifier. Voltage-controlled gain circuit composed of 2N5457:
