ABSTRACT:
The improved gain control circuit is comprised of an amplifier, a semiconductor device attenuator at the amplifier input, and unique control circuitry for controlling the attenuation factor of the semiconductor device. The amplifier is designed for low phase shift to minimize the time delay of its transfer function. The control circuitry responds to both positive and negative a.c. signal transitions at the amplifier output to initiate attenuator gain reduction. As with the amplifier, the control circuitry is designed for minimum response time. The combination results in an extremely fast a.g.c. attack time.
