Abstract :
This paper shows the feasibility of combining rotary traveling wave (RTW) oscillator and frequency switch tuning compensation based on a capacitor network to achieve a temperature and process variations robustness of voltage controlled oscillators (VCO). This concept has been proved by combining transistor level simulations for the active part and electromagnetic simulations for the transmission lines. Global system specification have also been checked with high level phase locked loop (PLL) modeling.
