Hi All,
I have read in many books that the Vt of MOSFET depends on channel length, Vsb, temp etc.

I would like to know whether there is any dependency on Width/Multiplier parameter of the MOSFET.

Recently in HSPICE simulation, I found that the Vt of an NMOSFET is different for the following cases

1. W=8u, L=0.36u & M=1
2. W=2u, L=0.36u & M=4

Waiting for your comments and post-topic replies.
