Abstract
There is described a driver for a switched capacitor circuit (), the driver comprising (a) a voltage amplifier () comprising a signal input (), a feedback input () and an amplifier output (), and (b) a feedback network () coupled between the amplifier output () and the feedback input (). The feedback network comprises a track-and-hold circuit () adapted to mask a voltage dip occurring at the amplifier output () at the beginning of a switched capacitor circuit charging phase. There is also described a switched capacitor circuit comprising such a driver, a sensor device, and a method of driving a switched capacitor circuit.
