Abstract
A pseudo-differential switched-capacitor circuit using integrator-based common-mode stabilization technique is disclosed. A pseudo-differential switched-capacitor circuit with the differential floating sampling (DFS) technique has a common-mode gain value of one (1). An integrator is electrically coupled to the differential positive/negative outputs of the DFS circuit, and the integrator feeds back integrator output to the DFS circuit by detecting common-mode voltage disturbance at the differential positive output (V+) and negative output (V−), thereby stabilizing output common-mode level of the differential positive output (V+) and negative output (V−) at a desirable level.
