MOSFET – importance and Types
A metal oxide semiconductor field effect transistor (MOSFET) is a active device i,e; it can control the flow of electron and in which there is a twin layer of SiO2 between the gate and the channel.
MOSFET Importance in VLSI
- For NMOS technology the design methodology and design rules are easily learned.
- Provides an excellent backgrounds for other technologies.
- For GaAs technology, some arrangements in relation to logic design are similar to those employed in NMOS technology.
Types of MOSFET
The MOSFET are classified into two categories.
- Depletion mode MOSFET
- Enhancement mode MOSFET . Both the two types are further classified into two categories – 1. P channel MOSFET and N channel MOSFET.
