如下图所示,我们可以直观看到能带在MOSFET中的表现,以NMOS为例,当加了Vgs电压时,Vgs将在Gate表面的能带向下拉(下面图中的第三个图例),使得电子更加容易穿过沟道,但由于此时Drain未加电压,能带位置没有发生变化,所以此时没有电流流过。当Drain加电压之后(下面图中的第四个图例),Drain处的能带被向下拉,从而从Source...
【题目】有一个Gate和Drain连接在一起的MOSFET,它的参数是VT和K。它的drain 答案 【解析】由於器件在开关状态的持续时间内既有大电流又有高电压,器件工作速度快,其损耗的能量就较少,仅这一个优势就能弥补高压MOSFET存在的导通损耗稍高的问题。相关推荐 1【题目】有一个Gate和Drain连接在一起的MOSFET,它的参数是...

MOS,是MOSFET的缩写。MOSFET金属-氧化物半导体场效应晶体管,简称金氧半场效晶体管(Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET)。一般是金属(metal)—氧化物(oxide)—半导体(semiconductor)场效应晶体管,或者称是金属—绝缘体(insulator)—半导体。G:gate 栅极;S:source源极;D:drain 漏极。 MOS管的so...
功率VDMOSFET管是三端管脚的电压控制型开关器件,在开关电源电路中的使用和双极型晶体管类似。其电气符号如图1,三端引脚分别定义为栅极(Gate),漏极(Drain)和源极(Source)。 图1、DMOS管电气符号 功率VDMOSFET管按照器件的栅结构,可以分为平面(Planar),沟槽(Trench)两大类。由于两者电参数定义相同,所以本文仅就Pla...
如上图,左边是一颗典型的平面SiC MOSFET芯片(宏观图)其中G区是栅极焊盘(gate pad),也就是引出栅极引线的地方,起控制作用。 AA是有源区(active area),其中AA的正面是源级区(source),键合源级引线过大电流; 背面是漏极区(drain),右图黑色部分代表背面金属(back metal),一般是钛镍银(TiNiAg)或者铝硅铜(AlSiC...

The grounded-gate or gate-assisted drain breakdown voltage of n-channel MOSFET's has been characterized for wide ranges of oxide thickness and substrate doping concentration. Two distinct regimes, one being channel-doping limited and the other being oxide-thickness limited, have been identified. We...
Gate current injection into the gate oxide of MOSFETs with a split-gate (virtual drain) structure is examined. The split-gate structure is commonly encountered in flash EEPROM and CCDs. An important parameter characterizing the gate current injection... 关键词: electric fields impact ionisation ins...
