In this thesis, mechanisms that cause LC Oscillator frequency sensitivity to supply noise is analyzed. It is proven that variations in both the common-mode and differential-mode components can increase the jitter in the presence of supply variations due to non-linearity of the capacitors that are in the oscillator. A novel compensation technique that reduces this sensitivity is presented. Simulations show that this technique can reduce the periodic jitter due to supply sensitivity by more than 80%.
