Abstract
Circuitry and techniques are described herein for performing accurate and low power conversion of an analog value into a digital value. According to some aspects, this disclosure describes a successive approximation register (SAR) analog to digital converter (ADC). According to some aspects the SAR ADC comprises an active integrator between a sample and hold stage and a comparator stage. The active integrator operates differently dependent on whether the SAR ADC is operated in a sample phase or a conversion phase. According to other aspects, the SAR ADC utilizes a ring oscillator-based comparator to compare a sampled analog input value to a plurality of reference values to determine a digital value representing the analog value.
