Voltage threshold
Below is an explanation for the
Threshold voltage increases for narrow NMOSFETs.
In the middle of the transistor, the field effect is similar to that for infinite
parallel plates. Near the edges, the fringing effect results in a higher required
voltage difference to achieve inversion. For narrow transistors, the
appropriate model moves from infinite parallel plates to a line and plate.
I don't really get it, can someone help me?
