Abstract
Disclosed herein are related to systems and methods for a power efficient successive approximation analog to digital converter (SAR ADC). In one aspect, the SAR ADC includes a sample and digital to analog conversion (DAC) circuit to sample an input voltage. In one aspect, the SAR ADC includes a first comparator coupled to the DAC circuit, and a first set of storage circuits coupled between the first comparator and the DAC circuit. In one aspect, the SAR ADC includes a second comparator coupled to the DAC circuit, and a second set of storage circuits coupled between the second comparator and the DAC circuit. In one aspect, the SAR ADC includes a control circuit configured to select, for each of multiple bits corresponding to the input voltage, a corresponding comparator to determine a state of the each of the multiple bits during a corresponding time period.
