Analysis of Ultralow-Power Asynchronous ADCs

Christian Enz, Aravind Prasad Heragu Singaiyengar

In this paper, analysis of a novel class of A/D converters based on asynchronous delta modulation (DM) is presented and a high level model is realized for the same. Using the high level model, analytical expressions are derived for the calculation of the i ...
