Shunt-Zero Based on CMOS Split-Drain: A Practical Approach for Current Sensing

Abstract

A current sensor circuit intended for integrated smart-power applications featuring galvanic isolation is devised. It is based on magnetic detection using the CMOS compatible split-drain transistors (MAGFET) that provides linear output current versus magnetic field from DC to several MHz range. An integrated sensor built in 0.35 mum CMOS technology… (More)
