Hello everyone,

This is my first post, so please bear with me. Hopefully, we all can learn something here.

I am a student of Electrical Engineering, and i working on a small research project. For the starters, i have been given an assignment in which i am suppose to find the parameters of an INVERTER that was fabricated using the cadence layout tool. But, the problem is that i have been taught how to find parameters using the circuit layout (using voltages and currents), not the fabrication layout (using fabrication dimensions).

All i have been given to do so is a print out of the layout, and the dimensions of different layers (Polysilicon, metal 1, metal 2 e.t.c.)

So my question is, is it even possible to calculate the parameters using JUST the dimensions of the layers? and if yes, what text should i read to find any equations or formulas that i need.

I just can not comprehend how it is possible to find the parameters of an INVERTER, just with the use of a print out of layout and the dimensions (Lambda) of the layers?

I am not asking for spoon feeding, i really just don't know where to even start. So, any leads would be really helpful.

Thank you.
