Title:
AUTOMATIC GAIN CONTROL CIRCUIT IN RECEIVER
Document Type and Number:
Japanese Patent JP2004023532
Kind Code:
A
Abstract:
To provide an AGC circuit whereby a proper gain control signal is obtained in a short time in a transient of a receiver such as at application of power.
The center point of a series capacitor circuit whose one terminal is connected to a power supply terminal and the other terminal to ground is connected to the output terminal of the AGC circuit. Properly selecting the capacitance ratio of two capacitors forming the series circuit sets the center potential of the series capacitor circuit to a gain control signal voltage of the AGC circuit in a steady state operation of the receiver.
