Abstract:
This disclosure relates to analog to digital conversion using irregular sampling. A method may include combining an analog signal with a feedback signal into a combined signal, filtering the combined signal using a digital noise shaping filter into a combined noise shaped signal, modulating the combined noise shaped signal into a modulated signal, generating samples of the modulated signal, and reconstructing as a digital signal the analog signal from the samples of the modulated signal.
