Hi guys,
I simulated the output resistance of MOSFET using TSMC018mm technology. I sweep Vds and use calculator to draw the output resistance vs. Vds. However, the curve is different with the DC operating point I print.
Here is the detail:
I set Vgs=Vds=1V, Vsb=0. Then I simulate and print the DC operating point to get ron. The pring result is:
ron=63k
However, from the output resistance curve(obtained by calculator) is 8.9M.
My question is:
1. Is ron(printed in the DC operating) the output resistance of MOSFET?
2. Why ron is different from the result obtained by calculator?
Regards,
Ming
