How to extract Threshold Voltage (Vth) and Gain Parameter(K') from a PDK

Hi all,

I am working on a RF project. I am using Cadence Virtuoso 6.1. I need to know the threshold voltage(Vth) and gain parameter(K' = u. Cox) from a transistor model in a library of a PDK. For examle I am using GPDK045, I want to know Vth and K' of cell NMOS1v. How could I do that? I need these paremeters to do some calculations for RF circuits

Thanks

You can find it yourself. Simply, do a DC simulation and find the uncox and vth of the transistor ( knowing that this is first order model). If you find the second derivation of Id(Vgs), this value should be equal to uncox(W/L).

Hi Milad-D.
What do u mean by DC simulation, How can I do that? Can you explain more about that. Do I have to connect the transistor with something or just transistor itself?
