An overview of switched-capacitor (SC) circuit applications is presented. SC functional blocks, which play an important role in many systems, are discussed. Several large-scale integrated circuits, which are mainly for commercial use, are outlined, placing stress on why SC circuits are used. These include codecs, modems, and speech analysis and synthesis circuitry. Projected future SC circuit performance is discussed in comparison with digital signal processing technology. Promising application fields are identified.
