Abstract:
A pseudo-differential switched-capacitor circuit, which can be applied to various signal processing circuits, employs a floating sampling technique and an integrator feedback loop for isolating a common mode voltage disturbance and restraining a charge injection effect. The pseudo-differential switched-capacitor circuit includes a differential floating sampling circuit that has a pseudo-differential architecture, and an integrator for reducing the charge injection effect within the differential floating sampling circuit.
