Hello,
I'm using mentor tools to design and simulate different properties and C/C's of VCO. When i try to simulate the phase noise on ELDO-RF with UMC 0.18u Design Kit, i get strange results: 1) The value of phase noise at 10Hz is over 0dB (actually it reaches 60dB or so) 2) The phase noise shape is somehow strange with the -30 and -20 dB/dec. slopes changed in some points....i realized that its due to the varactor but i want to know if there is a soln. here as the phase noise is degraded so much.
Please if anyone faced any of this reply.
Thanks in advance, Aboel3la
