Abstract
A gain control amplifier is shown to include a temperature compensation circuit and a feed forward gain control loop. With such an arrangement, a gain control amplifier is provided wherein variations of an output signal of the amplifier are minimized due to changing characteristics of the amplifier caused by ambient temperature variation or from a varying input signal level.
