Abstract: A multi-stage Successive-Approximation Register (SAR) pipeline Analog-to-Digital Converter (ADC) has an amplifier between two switched capacitor networks, each controlled by a SAR. The load capacitance of the amplifier is magnified due to the amplifier's gain. This magnified load capacitance can disproportionately increase power consumption. The back plates of the second-stage switched capacitors are connected to the amplifier input using a feedback switch during an amplification phase, so that the second-stage switched capacitors are connected between the input and output of the amplifier as a feedback capacitor, rather than a load capacitor. Reset switches are added to drive both plates of the second-stage switched capacitors to ground during a reset phase before the amplification phase. Thus the second-stage switched capacitors function as both the feedback capacitor and as the switched capacitors controlled by the second SAR.
