Hello,
I am design a LC VCO which the oscillation frequency is about 40GHz. In such a high frequency, the problem that i meet is, firstly, how to get accurate inductor, does it need to simulate the inductor model in HFSS to get it S_parameters, and how to get it? Secondly, with the experence of my first work, the oscillation is lower than the desired, may the parastic cap results it, what should I do to reduce this effect. Last one, At mm frequency, does it need some special methods for VCO design?
Thank u for your reply!
