Abstract
A multi-bit continuous-time sigma-delta modulator, SDM, includes an input configured to receive an input analog signal; a first summing junction configured to subtract a feedback analog signal from the input analog signal; a loop filter configured to filter an output signal from the first summing junction (304): an analog-to-digital converter, ADC, configured to convert the filtered analog output signal to a digital output signal; and a feedback path for routing the digital output signal to the first summing junction. The feedback path includes a plurality of digital-to-analog converters, DACs, configured to convert the digital output signal to an analog form. The ADC comprises a plurality of N-bit comparator latches that are each locally time-interleaved with at least a pair of latches and configured to function in a complementary manner and provide a combined complementary output.
