12 Introduction to switched -CapacitorCircuitsOur study of amplifiers in previous chapters has dealt with only cases where the input signal iscontinuously available and applied to the circuit and the output signal is continuously continuous-time Circuits , such amplifiers find wide application in audio, video, and high-speed analog systems. In many situations, however, we may sense the input only at periodic instantsof time, ignoring its value at other times. The circuit then processes each sample, producing avalid output at the end of each period.
