以平面增强型N沟道MOSFET为例,基本结构如下图所示。可以看到,从左到右为NPN的掺杂,在扩散作用下,会自然形成像图中所示的深红色的耗尽区(depletion region),根据前面所述,耗尽区是不能导电的,因此漏极(Drain)到源极(Source)在未加外加电场的时是断开的,因此该结构是Normal off的结构。 MOSFET normal off 注意...
linear region1/f noiseunified modelThis paper presents results of low frequency noise measurements for a Dual-Gate MOSFET (DGMOSFET) in linear region. DGMOSFET working conditions are chosen in order to set both inner transistors in linear regime. Results are discussed with the use of the ...
MOSFETs have to be specifically rated to operate in the linear region and have safe operating curves well below the maximum power rating when used as an electronic switch.[1-2] Circuitry for MOSFET loads requires each stage to be controlled in a closed loop to linearize the response. As ...
The MOSFET operates as a voltage-controlled current source in its active region, where the gate-to-source voltage regulates the drain current. This ...
