关于MOSFET的一些常识 MOSFET 金属-氧化层-半导体-场效晶体管，简称金氧半场效晶体管（Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET）是一种可以广泛使用在类比电路与数位电路的场效晶体管（field-effect transistor）。MOSFET依照其“通道”的极性不同，可分为n-type与p-type的MOSFET，通常又称为NMOSFET...
holes. The depletion layer’s region width will affect the conductivity value of the channel. So, by variations of the region’s voltage values, the flow of current gets controlled. At last, the gate & the drain will stay at the negative polarity while the source remains at the ‘0’ ...
