Tearing Into Delta Sigma ADC’s

It’s not surprising that Analog to Digital Converters (ADC’s) now employ several techniques to accomplish higher speeds and resolutions than their simpler counterparts. Enter the Delta-Sigma (Δ∑) ADC ...

Understanding Continuous-Time, Discrete-Time Sigma-Delta ADCs And Nyquist ADCs

Sigma-delta converters are in wide use among applications that demand high precision and accuracy. A variant of the sigma-delta architecture, called the continuous-time sigma delta (CT-S?), has found ...

ADC Basics, Part 2: SAR & Delta-Sigma ADC Signal Path

Generally, you will find the SAR (successive-approximation-register) and delta-sigma (??) analog-to-digital converters (ADCs) in lower frequency applications. The signal chain for these applications ...

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 ...
