ABSTRACT:
A configurable switched capacitor block includes a switched-capacitor (SC) sampling circuit, a fully differential amplifier, an SC feedback circuit, and a comparator. The SC sampling circuit is coupled to receive an input signal and to selectively generate a sampled signal to a differential input of the amplifier. The SC feedback circuit is coupled between the differential inputs and the differential outputs of the amplifier to selectively control a feedback of the amplifier. The comparator is coupled to the differential outputs of the amplifier to generate an output signal. The configurable switched capacitor block has multiple modes of operation which are selectable by programming the SC sampling circuit and the SC feedback circuit.
