Patent abstract
An automatic gain control (AGC) system and method for implementing a wide dynamic range automatic gain control (AGC) are disclosed. The AGC system features a large gain adjustment suitable for integration in silicon tuners. The AGC structure employs a pair of classical current steering stages, architecturally arranged to share the gain back-off characteristic in a novel “ping-pong” arrangement. The AGC system and method deliver a wide dynamic range at low power dissipation in radio frequency (RF) systems, but may be implemented as well in other applications.
