摘要
Herein disclosed are some examples of metastability detectors and compensator circuitry for successive-approximation-register (SAR) analog-to-digital converters (ADCs) within delta sigma modulator (DSM) loops. A metastability detector may detect metastability at an output of a SAR ADC and compensator circuitry may implement a compensation scheme to compensate for the metastability. The identification of the metastability and/or compensation for the metastability can avoid detrimental effects and/or errors to the DSM loops that may be caused by the metastability of the SAR ADCS.
