A digital gate driver (DGD) is an important technology to reduce both switching loss and voltage and/or current overshoot. In this paper, a 5 V, 300 MSa/s, 6-bit DGD IC, where the gate current is varied in 64 levels for each of 16 3.3-ns time interva

A dual-path hybrid DC-DC converter with the step-down ratio of less than half is proposed for the first time. In the proposed converter, the efficiency is higher than a conventional buck converter, because the output current is divided into inductor-
