Abstract
A multi-stage switched capacitor circuit and an operation method thereof are provided. The multi-stage switched capacitor circuit includes a first operational stage, a second operational stage and a third operational stage that are serially connected in order. Each operational stage operates in a sample phase or a hold phase and generates a detection signal indicating an end of the hold phase. The operation method of the multi-stage switched capacitor circuit includes: controlling the second operational stage to operate in the hold phase when the detection signal of the first operational stage indicates the end of the hold phase of the first operational stage, and the detection signal of the third operational stage indicates the end of the hold phase of the third operational stage.
