A previous design had a 14 bit ADC that was sampled at a rate of 1 MHz. You would like to replace it with a 12 bit ADC, but maintain the same signal to noise ratio by oversampling. What does the ...

Step-by-step approach to building a CTSD modulator loop. Introducing the analog accumulator. A closer look at oversampling and noise shaping. The clock sensitivity of CTSD ADCs. 1. A closed-loop op ...

Atmel’s AVR controller offers an Analog to Digital Converter with 10-bit resolution. In most cases 10-bit resolution is sufficient, but in some cases higher accuracy is desired. Special signal ...

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 ...
