Simulate fmax of a MOSFET

Pyroblast

Hi guys,

I want to simulate the fmax of a mosfet. Does anyone know how this can be done? Can someone give me a tip?

Best.

    Hi Andrew, I took a look at your colleague blog and to be honest and with all respect that blog doesn't say absolutely nothing about how to simulate the Fmax of a mosfet. Absolutely nothing. I have put together all the components. It doesn't say which analysis to perform, how to configure, doesn't say if we need to use any expression and it's funny that the author says:

    "So, for example, we can measure ft directly in simulation instead of extracting it from s-parameters as we would have to do if we tried to measure it in the lab. On the other hand, simulation also ignores all the higher order device behavior that designers do not specify. As a result, effects that can degrade design performance are ignored."

    but doesn't tell how.

    I took a look the the other entries in his blog and the same applies.

    So I remain in the same step.

    Any other suggestion?

    Regards
