摘要：
An electronic circuit includes a first variable gain amplifier for amplifying a signal at an input to provide a first amplified signal; a filter receiving the first amplified signal to provide a filtered signal; a second variable gain amplifier for receiving and amplifying the filtered signal; a second gain control bock, to provide at least one gain control signal derived from the filtered signal, one of the at least one gain control signal to control the gain of the second variable gain amplifier; and a bounding block for receiving one of the at least one gain control signal from the second gain control block, and for generating therefrom a bounded gain control signal to control gain of the first variable gain amplifier.
