In this paper, a problem of huge voltage overshoots (V OVERSHOOT ) of VDS in GaN FETs, which rarely happens during an automatic search of optimum gate driving parameters in a digital gate driving (DGD), is clarified for the first time, and a solution

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
