The patent describes an electronic gain control circuit having first and second differential amplifiers and an operational amplifier. The first differential amplifier is coupled to the input and provides the controlled output. The second differential amplifier is coupled to the first differential amplifier and controls the gain of the circuit. The operational amplifier is coupled to the second differential amplifier for temperature stability and linearity.
