Zusammenfassung:A time-interleaved analog-to-digital converter (ADC) includes a plurality of ADC blocks each including: at least one ADC unit configured to convert an analog input to a digital output; and a digital gain controller configured to adjust a reference voltage of the at least one ADC unit based on a comparison of an actual output of the at least one ADC unit to an expected output of the at least one ADC unit.
