Hi, i'm looking for a good desing for VCO at 0.35 CMOS technology, and i have meet with ring oscillators and differential LC tanks are more usual implementation. According phase-noise, which be better?.
Also i'm looking for implementations that meet a levels of phase noise lower than -110 dBc/Hz, offset 25 kHz at GSM frequency (or approx, I don't sure).
I thank in advance your constructive answers.
