Abstract: A modulo-based ADC implementation is provided and involves converting an input analog signal into phases of other M periodic analog reference signals based on one or more transfer functions, wherein M≥2. The phase of each of the M reference signals comprises a folded signal corresponding to the input analog signal that is amplitude-folded to fall within a required amplitude range. This signal-to-phase conversion allows a modulo operation to be implemented over the input analog signal. Further, the M reference signals are used to obtain M discrete-time digital signals which, in turn, are used to obtain a digital representation of the input analog signal.
