Abstract
When the operating speed of a switched capacitor circuit is accelerated, the timing of the clock signals regulating switched capacitor circuit operation can be disrupted by the effects of variation introduced by the manufacturing process as well as parasitic resistance and parasitic capacitance on signal traces. A control signal generating unit adjusts the timing of the bottom plate sampling period and non-overlapping period of the clock signals supplied to operate the switched capacitor circuit, thus avoiding disrupting the control signal timing and affording a switched capacitor circuit without increasing the area of the logic devices that set the bottom plate sampling period and non-overlapping period.
