Abstract
Techniques and apparatus for alias rejection in analog-to-digital converters (ADCs), in which only a portion of the ADC is operated at a higher sampling rate than other portions of the ADC, thereby preventing aliasing, but saving power. One example ADC circuit generally includes a first circuit portion configured to operate at a first clock rate equal to a sampling rate of the ADC circuit; and a second circuit portion configured to operate at a second clock rate higher than the sampling rate of the ADC circuit.
