Hi!Why 'gate width' is important in amplifier or mosfet? large gate width or small gate width which is good and why?
THS!
-CQCQ
The W term refers to the gate width of the transistor. As you can see, increasing the gate width will increase the drain current of the transistor. The benefits of a higher drain current should be obvious.
The transconductance of the n-type MOSFET in saturation is given by:
Once again, there is a linear relationship between transconductance and transistor gate width. A higher transconductance means that you can build an amplifier with a higher gain.

More is the gate width more is the transconductance of the device....
as the gate width increase that mean more current can pass through ur device , and also the transcondacutanc
this means higher gain
