Weband drain. For power MOSFETs, it is usually measured at the drain-source current of 250uA. Gate oxide thickness and doping concentration of the channel can be used to control the V . Typically, 2~4V is designed for gate drive of 10-15V. With the scaling down of the CMOS technology, the gate drive of the power MOSFET drops to 2.5-4.5V. Therefore, WebFigure 3.13 shows the state-of-the-art trade-off between and BV of standard power MOSFETs and theoretical silicon limit, respectively [].The superior switching performance of the power MOSFET ensure that it has become a key device in the field of SMPS. However, as can be seen in the figure, the on-resistance of power MOSFETs increases sharply …
