Mosfet active region
WebIdentifying Cut off, Ohmic and Saturation Regions in E-MOSFET WebWith some hand waving, we can say electrons can easily flow from n regions to p regions, as long as they have a little force (voltage) to push them.But flowing from a p region to an n region is really hard (requires a lot of voltage). But the special thing about a transistor -- the part that makes our two-diode model obsolete -- is the fact that electrons can easily …

WebWhat are the three regions of operation in MOSFET? Cut-off region: When VGS < Vt, no channel is induced and the MOSFET will be in cut-off region. No current flows. Triode region: When VGS Vt, a channel will be induced and current starts flowing if VDS > 0. MOSFET will be in triode region as long as VDS < VGS Vt. The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device.
