Summary:A current-mode CMOS RMS-DC converter is presented. The basic building blocks are based on a novel approach to design current-mode computational cells. In such an approach, the large-signal V-I characteristic of class-AB transconductors is conveniently exploited leading to a very regular and compact implementation. A proper biasing scheme in such transconductors allows operation with supply voltage as low as V/sub GS/+2V/sub DSsat/. Measurement results from a practical prototype are presented in order to demonstrate the technique proposed here.
