Hi Guys:
I had initially used damped periodic vsin source to initialize the designed pMOS based VCO, the transient response are of satisfactory from 0-1.8V of tuning voltage, but due to its nature of damped periodic, I had difficulities in executing the PSS analysis, I shifted to a pulse source initialization at the Vdd and a pulse current source in parallel to the LC tank, the transient response however is not of satisfactory from 0-1V of tuning voltage. but however there is variation of frequency with respect to the variation of the tuning voltage. Can anyone kindly comment on this?. Thanks in advance
