Fully Digital implemented Delta-Sigma Analog to Digital Converter

One of the most challenging tasks in Analog to Digital Converter (ADC) design is to adapt the cicuitry to ever new CMOS process technology. For digital circuits the number of gates per square mm app. doubles per chip generation. Integration of analog parts in newer deep submicron technologies is much more tough and additionally complicated because the usable voltage ranges are decreasing with every new integration step.
