Abstract
Systems and methods for an asynchronous successive approximation register analog-to-digital converter (SAR ADC) with word completion algorithm may include a SAR ADC comprising a plurality of switched capacitors, a comparator, a metastability detector including a timer having a tunable time interval, and a successive approximation register. The SAR ADC may sample input signals at inputs of the switched capacitors and compare signals at outputs of the switched capacitors. The SAR ADC may also determine, based on a value of a tunable time interval, whether to set a metastability flag for a first bit to be evaluated and update the value of the tunable time interval based on whether the metastability flag was set.
