In synchronous buck converters, a MOSFET’s gate resistance (Rg) has significant influence on system losses and loss mechanisms. Using mathematical treatment and laboratory examinations, Elbanhawy’s conference paper will examine the effect of Rg on current distribution on the die and current rise and fall times, which influence the dynamic losses, and also the effect of Rg on shoot through in the synchronous buck converter.
