    Abstract: The channel resistance of a metal-oxide-semiconductor fieldeffect transistor, or other insulated gate field effect transistor, is linearized by applying to the gate electrode, in addition to the gate voltage for controlling the conductivity, an external feedback voltage having a value of one-half the supply voltage to nullify the effect of the internal feedback due to the supply voltage. In some cases the base electrode is disconnected, but spurious effects caused thereby can be avoided. The voltagecontrolled linear resistor can be employed in DC and AC circuits in applications such as an AC phase shift circuit.
