hi everybody：
I need to design a qvco which works at 25Ghz,and i use the IBM 0.13um Bicmos technology,but something wrong happened when I simulated.There are three questions.
first.when I simulated the vco using S-qvco and P-qvco architecture, but I canÂ’t simulate S-qvco better than P-qvco, I can only simulate S-qvco for -93dBc@1M，P-qvco for -100dBc@1M,how to optimize it.
second. using cadence to simulate the in cadence,the phase noise derivate more than 10dBc for different pss simulation time,etc 100ns,200ns,300ns
third. I cant using APS to accelerate while simulating in cadence, are there something mistakes setting
have anyone met this question before.
please contact with me if you know it.thanks for help.
best wishes
