Abstract: Various aspects facilitate gain adjustment associated with an analog to digital converter. A capacitor array comprises a plurality binary-weighted capacitors and generates an output voltage received by a comparator based on an input voltage and a reference voltage. A gain calibration component receives the input voltage and applies a modified input voltage that corresponds to a portion of the input voltage to the output voltage generated by the capacitor array component.

Abstract: Various aspects facilitate error reduction for an analog to digital converter (e.g., due to metastability). A digital to analog converter generates a scaled reference voltage based on a reference voltage. A comparator component performs a comparison between an input voltage and the scaled reference voltage based on a defined period of time to perform the comparison.
