ABSTRACT:
A DC offset cancelling circuit with multiple feedback loops suppresses DC offset voltages within an automatic gain control loop apparatus. The apparatus includes a plurality of gain stages connected in series that receive and amplify an input RF signal. Each gain stage includes a corresponding feedback loop to filter the DC offset voltage accumulated in the respective gain stage.
