Abstract
A switched-capacitor (SC) circuit relating to summing and integration algorithms is provided. The SC circuit submitted by the present invention benefits from better closed-loop bandwidth performance because of combining positive and negative feedback loops of a high gain amplifier. In addition, the SC circuit submitted by the present invention not only provides differential output signal obtained by a summing (or integration) algorithm of input voltage signals and reference voltage signals and forward drives such differential output signal to a next stage SC circuit, but also provides flexible and accurate coefficient design for every individual input and reference voltage signals in the said algorithm. Besides, if the circuit manner of alternate resetting is disabled or removed, the SC summing circuit submitted by the present invention can serve as an SC integration circuit.
