Effect of gate resistance
WebJan 9, 1999 · Abstract. A physics-based effective gate resistance model representing the non-quasi-static (NQS) effect and the distributed gate electrode resistance is proposed … WebPower supply designers can sometimes gain additional efficiency increases by properly matching the gate drive voltage with the MOSFETs being driven. Driving a MOSFET gate with a higher voltage, results in a lower associated on-resistance, RDS(on), up to a particular point of diminishing return. This can be extremely
