This article is the last in a brief overview of the inner workings of delta-sigma ADCs. You have seen how the modulator operates in the time and the frequency domains and how it shapes the ...

The requirement of effective analog to digital conversion and accuracy gives growth to converters. The sigma delta modulator have a salient feature of shaping the noise, such that noise reduces from ...

This in-depth article covers the theory behind a Delta-Sigma analog-to-digital converter (ADC). It specifically focuses on the difficult to understand key digital concepts of over-sampling, noise ...

Based on the amount of e-mail I received after Part 3 of this series (Nov. 7, 2008, p. 18; www.electronicdesign.com, ED Online 19948), many of you have already guessed that an incremental integrator ...

My last column showed how a single-stage delta-sigma modulator (DSM) produces an output that is a sum of the low pass-filtered input signal and the high pass-filtered quantization noise (see “Part 4,” ...
