Abstract
Methods and systems are described for providing an analog-to-digital converter that uses reduced power and supply voltage. The analog-to-digital converter includes a sample phase configured to sample an incoming analog signal having an input signal range and compare the incoming analog signal to a reference voltage. The analog-to-digital converter also includes a feedback phase wherein the feedback phase receives sampled signal data corresponding to the incoming analog signal from the sample phase and is configured to produce an output signal comprising an output signal range, wherein the output signal range is equal to one half of the input signal range, and wherein the analog-to-digital converter has a feedback factor that is substantially greater than ⅓.
