Fast startup RF blocks with Low Supply Noise Sensitivity for Internet of Things Applications
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%.
