20100164761DUAL-USE COMPARATOR/OP AMP FOR USE AS BOTH A SUCCESSIVE-APPROXIMATION ADC AND DAC - A re-configurable circuit acts as an Analog-to-Digital Converter (ADC) and as a digital-to-analog converter (DAC). An array of binary-weighted capacitors stores an analog input. Switches connect different capacitors in the array to fixed voltages that cause charge-sharing with a terminal capacitor. The voltage of the terminal capacitor is compared by a re-configurable comparator stage for each different combination of the capacitors. The comparison results are analyzed to determine the closest digital value for the analog input. In DAC mode, the array capacitors are switched based on an input digital value. The switched capacitors connect to a charge-sharing line to generate an analog voltage that is applied to the re-configurable comparator stage. A differential amplifier generates a buffered analog voltage that is fed back to the other input of the re-configurable comparator stage for unity gain. The gain of the re-configurable comparator stage adjusts for ADC and DAC modes.07-01-2010
