Abstract
Low supply voltages in modern CMOS technologies are expected to reduce the maximum resolution of analog to digital converters in voltage mode operation. This paper outlines the functionality and possibilities of switched current (SI) circuit techniques in medium accuracy ÎΣ modulators. Starting with the presentation of different kinds of switched current cells, this paper gives an overview about the simulated performance followed by a comparison of switched current and switched capacitor circuits. A prospect of the future of switched current circuits with regard to future CMOS technologies is given.
