Abstract

A continuous time, sigma-delta analog-to-digital converter circuit includes a sigma-delta modulator circuit configured to receive an analog input signal. A single bit quantizer of the modulator generates a digital output signal at a sampling frequency. A data storage circuit stores bits of the digital output signal and digital-to-analog converter (DAC) elements are actuated in response to the stored bits to generate an analog feedback signal for comparison to the analog input signal. A filter circuit includes polyphase signal processing paths and a summation circuit configured to sum outputs from the polyphase signal processing paths to generate a converted output signal. A fan out circuit selectively applies the stored bits from the data storage circuit to inputs of the polyphase signal processing paths of the filter circuit.
