An Analog-to-Digital Converter (ADC) is an active interface between the analog and digital signal chains in an embedded system. An ADC converts analog signals into digital signals in electronic ...

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 ...

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 ...

It’s a counterintuitive result that you might need to add noise to an input signal to get the full benefits from oversampling in analog to digital conversion. [Paul Allen] steps us through a simple ...
