摘要

This paper presents a fast-response full-wave inductor current sensor for a DC-DC converter operating in 10 MHz switching frequency. It can achieve high sensing accuracy better than 93% with inductor current varying from 100mA to 2.1 A. Also, the time response of proposed current sensor has been greatly improved and achieved <; 8 ns for sensing full wave inductor current with a low transition spiking.
