now, I am designing a cmos vco which works at 8Ghz(highest freq, wideband),using TSMC 0.13um cmos process.but I don't use this process before,so I now don't make sure how much parasitical capcitance I need to consider,who can help me?
thanks
I personally suggest that you just design it and get some feelings. In fact, 8G Hz is not that high for .13um process, and I guess you still need to add MIM caps into the resonant, so that even though you find the parasitic cap is large in post simulation, you can simply decrease some MIM caps.
