Loading-free multi-stage SAR-assisted pipeline ADC that eliminates amplifier load by re-using second-stage switched capacitors as amplifier feedback capacitor
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. Amplifier power is reduced since there is no separate load capacitor during the amplification phase. |
