WebHow does MOSFET control voltage? MOSFETs have also been used as voltage-controlled resistors. Because most MOSFETs today tend to be “enhancement mode”, this means that the required biasing at the gate is a positive voltage to turn on the drain current to lower its R ds. Thus, if the gate voltage is 0 volts, the MOSFET is turned off.
WebThe voltage gain is equal to the negative of the product of transconductance and resistance.
WebThe voltage at gate controls the operation of the MOSFET. In this case, both positive and negative voltages can be applied on the gate as it is insulated from the channel. With negative gate bias voltage, it acts as depletion MOSFET while with positive gate bias voltage it acts as an Enhancement MOSFET.
