Abstract
Certain aspects provide a circuit for analog-to-digital conversion. The circuit generally includes a flash analog-to-digital converter (ADC) having a plurality of comparators, each comparator being configured to compare an input voltage to a reference voltage; and a calibration circuit coupled to the flash ADC and configured to tune the reference voltage prior to a conversion operation by the flash ADC.
