ABSTRACT:
A temperature-independent gain control circuit includes a dual-gate MOSFET having the input signal applied to one gate and a resistance connected to the source. Control means are provided which are responsive to a control voltage to control the voltage between the other gate of the MOSFET and the end of the resistance remote from the source in such a manner as to maintain the drain current of the MOSFET proportional to the control voltage.
