Abstract
An analog signal processing circuit can include a front-stage processing module configured to process an analog signal to generate a first differential signal; at least one switched capacitor circuit, coupled with the front-stage processing module to receive the first differential signal, and configured to integrate or sample and hold the first differential signal to generate a second differential signal; and where the front-stage processing module and the at least one switched capacitor circuit receive synchronous control signals, the front-stage processing module chops the analog signal according to the control signals, and the at least one switched capacitor circuit is in different operating modes at a first phase and a second phase of an operation cycle of the control signals, in order to eliminate DC offset voltages of the front-stage processing module and the at least one switched capacitor circuit.
