Abstract
The A/D convener has a digital output for outputting a digital output signal selected from a set of three or more available values. A feedback loop generates the digital output signal so that a time averaged difference between an analog input signal and an analog feedback signal representative of the digital output signal is minimized. A feedback signal generator generates successive signal levels of the feedback signal. A return to zero switch inserts predetermined return to zero levels between the signal levels in the feedback signal. The return to zero switch is also used to provide the signal level for one of the available values.
