hi,
I have used T-spice equivalent to H-spice but option of Phase noise measurement is not their.So have to calculate it theoretically with the values of current and other parameter.This theoretical values are nearly equal to the practical values only if we avoid any calculation error. Once I have verified the theoretical value with the simulation value in Cadence RFSpectre it came about nearly the same.If u need any help regarding theoretical calculation do revert back.
