Unleash the Performance Benefits of Sigma-Delta ADCs into Your SoC

Unleash the Performance Benefits of Sigma-Delta ADCs into Your SoC

Sigma-delta analog-to-digital converters (ADCs) deliver high resolution with low silicon area and power consumption, taking advantage of high-speed operation and digital signal processing common in modern digital system-on-chip (SoC), making them ideal for implementations in deep sub-micron processes. However designers are sometimes reluctant to use sigma-delta ADCs because of their unconventional architecture and apparently chaotic internal operation. This paper will give SoC designers a clear understanding of the workings inside sigma-delta ADCs and explain when they are a better alternative than other ADC architectures used in advanced, deep sub-micron SoCs.
