In one embodiment, an analog-to-digital converter includes: a sum circuit to receive an analog input signal and a feedback reference signal and generate a sum signal; a feedback circuit coupled to the sum circuit to provide the feedback reference signal to the sum circuit; a filter coupled to the sum circuit to receive the sum signal and generate a filtered signal; and a punctured quantizer coupled to the filter to receive the filtered signal and quantize the filtered signal to a digital output and to output the digital output and to provide the digital output to the feedback circuit.
