Delta-Sigma Modulation in CMOS Technology

Delta-sigma modulation has emerged as a pivotal technique in CMOS technology for high-resolution analogue‐to‐digital conversion. By utilising oversampling and noise-shaping strategies, this method ...

Sigma-delta techniques extend DAC resolution

Motion control systems often require digital-to-analog converters with high resolution but not high accuracy. Because high-accuracy DACs are expensive and consume valuable board space, a good solution ...

Using Delta-Sigma Can Be As Easy As ADC (Part 2)

In my previous column, I took a historical approach to delta-sigma modulation with the single-slope converter (May 8, p. 18, ED Online 18747). Jim Williams of Linear Tech responded, and he sent me a ...

D/A Converter Enhances Sound Quality

Audio D/A converters using sigma-delta conversion techniques are not new, so designers have learned to deal with some of the problems that are inevitable in their implementation. But now Wolfson ...

Using Delta-Sigma Can Be As Easy As ADC (Part 5)

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,” ...
