Abstract

A continuous-time delta-sigma modulator (CTDSM) system includes a quantizer, an update block, a switching block, a summation block, and a feedback path. The quantizer is configured to quantize an analog input signal into one or more thermometer-coded digital signals. The update block is configured to generate control signals based on the thermometer-coded digital signals. The switching block is configured to route the thermometer-coded digital signals to a plurality of digital-to-analog converter (DAC) elements based on the control signals. The plurality of DAC elements is configured to convert the thermometer-coded digital signals into analog outputs. The summation block is configured to combine the analog outputs from the plurality of DAC elements to produce a final analog output. The feedback path is configured to use the final analog output as a feedback signal for the CTDSM system.
