In part one, I compared the different Analog to Digital Converters (ADC) and the roles and properties of Delta Sigma ADC’s. I covered a lot of the theory behind these devices, so in this installment, ...

Shown is a simplified continuous-time sigma-delta ADC model, comprising a sigma-delta modulator and a decimation filter. The DT-S? input structure typically implements switched capacitors, and CT-S?

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 ...

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 ...

All real world signals are analog. The processing is, however, done in the digital domain for most applications. Hence a good interface, an Analog to Digital Converter (ADC) is very much essential.
