Automatic gain control of a receiver circuit

摘要

The receiver circuit for processing of electrical signals comprises an antenna (12), at least one amplifier (14) coupled to the output of the antenna (12), an automatic gain control circuit (30) coupled to the at least one amplifier (14) to modify a gain thereof, and at least one voltage offset-compensating circuit (50) embedded in the automatic gain control circuit (30). The receiver circuit further comprises a clock generator (40) and at least one capacitor (42, 44) to effectively compensate an offset voltage.
