Abstract
The gain factor K of the power MOSFET is an electrical parameter that mathematically speaking connects V GS to I D. Practically, higher is K higher will be I D fixing V GS, V TH and all the others physical and electrical parameters. K is a very important electrical parameter regarding the power MOSFET working in linear operating zone. In fact, even if, typically, higher K factor needs in switching operation mode, in linear zone, instead, K must be low to avoid a possible premature failure of the device. © 2012 IEEE.File in questo prodotto:
