Switched capacitor filters have now been around for a decade and many powerful and sophisticated design techniques have been developed. In view of the excellent literature on this subject to which the reader may refer, the present chapter has the rather specific aim of presenting some advances developed by the authors which have made a contribution towards extending the limits for switched capacitor filters beyond the generally accepted performance boundaries shown in Figure 4.1. The areas of performance improvement considered include performance precision, maximum achievable Q-factor and maximum operating frequency.
