Determining the resistance of the LC Tank

[gk1994]

I am designing a cross-coupled VCO. The first step is to get the resistance of the LC tank using S parameters in cadence.

My question is that, what are the other techniques where we can get to know the resistance of the LC tank in cadence virtuoso other than S parameter technique

Please let me know

Thanks!

Do you want to know the DC resistance or AC impedance at the resonant frequency?

 

[gk1994]

i would like to know both

 

[PETERDECO]

What are the values of the inductor and capacitor, and what is the frequency?

 

[gk1994]

38Ghz frequency with L - 150pH and C - 250fF. I would like to know how to do it in cadence

 

[PETERDECO]

That I don't know how to do. If your frequency was KHZ or MHZ and C + L was uF and H or uH I could tell you.

Yeah please take any value of your choice and let me know
