Hai Folks:
I had simulated the phase noise of a LC-QVCO using cadence spectreRF, with a pulse source perturbation. But I'm getting positive phase noise for offset frequency less than 100Hz. I thought the phase noise plot is a normalized plot of the carrier. It should start from 0 at 1Hz of offset and falloff negative. Why does this happen?
