WebEnhancement MOSFET Physical Structure : Figure below shows the simplified structure of the NMOS transistor. The NMOS transistor is fabricated on a p type substrate called as 'bulk' or 'body'. The two heavily doped n + regions are diffused in the p type substrate which forms the source and drain terminals. WebJun 12, 2013 · A MOSFET also contains a BJT: If the drain current is high, then the voltage across the channel between the source and the drain can also be high, because R D S ( o n) is non-zero. If it's high enough to forward-bias the body-source diode, you don't have a MOSFET anymore: you have a BJT. That's also not what you wanted.

WebA mosfet device has three different regions of operation. These regions are called the: Ohmic/Triode region, Saturation/Linear region and Pinch-off point. For a mosfet to operate as a linear amplifier, we need to establish a well-defined quiescent operating point, or Q-point, so it must be biased to operate in its saturation region. Webenergy band theory and the gradual-channel model of the MOSFET as well as advanced concepts and devices such as MOSFET short-channel effects, low-dimensional devices and single-electron transistors. Concepts are introduced to the reader in a simple way, often using comparisons to everyday-life experiences such as simple fluid mechanics.
