In typical LC VCO, L and C values are selected according to the formula f=1/√LC. How to find the PMOS varactor width values?. Also oscillation frequency versus control voltage is plotted for this VCO. very small variation in the oscillation frequency only obtained. Anybody give me any example fiile for differential LC VCO in ADS.
