ABSTRACT
This chapter introduces and analyzes an oscillator topology demonstrating an improved phase noise performance. It exploits a time-variant phase noise model with insights into the phase noise conversion mechanisms. It establishes the environment to introduce the class-F3 oscillator and explains circuit-to-phase-noise conversion mechanisms, and presents extensive measurement results of the prototype. The Q-factor of the complex tank, which comprises two coupled resonators, does not appear to be as straightforward in intuitive understanding as the Q-factor of the individual physical inductors. It is, therefore, imperative to understand the relationship between the open-loop Q-factor of the tank versus the Q-factor of the inductive and capacitive parts of the resonator.
