Sigma-delta ADCs come in 16 to 24-bit resolution, and they are economical for most data acquisition and instrument applications. Figure 2.03 (2.04) Integration time Discharge time

ume.gatech.eduHow does it work Input is over sampled, and goes to integrator. The integration is then compared to ground. Iterates and produces a serial bit stream Output is a serial bit stream with # of 1’s proportional to V in With this arrangement the sigma-delta modulator automatically adjusts its

Until recently, however, the process technology needed to make these devices commercially viable has not been available. Now that 1 micron and
Delta-sigma ADCs in a nutshell
www.rpi.eduDelta-sigma ADCs in a nutshell Part one of a three-part series exploring the basic topology and functions of delta-sigma ADCs. By Bonnie Baker -- EDN, 12/14/2007 Delta-sigma converters are ideal for converting signals over a wide range of frequencies from dc to several megahertz with very-high-resolution results.
