Abstract

See full text

A device (e.g., SAR ADC device) include a DAC circuit and generates a digital output based on logic circuitry that includes SAR logic. Additional logic circuitry includes delta modulation circuitry and dynamic element matching circuitry. The delta modulation circuitry provides several digital outputs of the SAR DAC, while the dynamic element matching circuitry selects a different set of capacitors from the DAC circuit. Each cycle is added together and averaged, and then added to the digital output from the SAR logic.
