Switched capacitor (SC) techniques are well proven to be excellent candidates for implementing critical analogue functions with high accuracy, surpassing other analogue techniques when embedded in mixed-signal CMOS VLSI. Conventional SC circuits are primarily limited in accuracy by a) capacitor matching and b) the accuracy with which a differential amplifier can squeeze charge from one capacitor to another between clock periods.
In Switched-C...
