Abstract
A receiver having an analog to digital converter with adjustable reference voltages that are calibrated to account for process variations. The receiver comprises an analog to digital converter. The analog to digital converter includes a reference generator to generate a set of N reference voltages. The reference generator adjusts voltage levels of the set of N reference voltages based on one or more control signals. A plurality of comparators compare an input signal to the set of N reference voltages. A calibration circuit generates the one or more control signals for adjusting the voltage levels of the N reference voltages based on outputs of the comparators.
