Abstract :
This paper presents an analysis that confers new insights into injection pulling and locking of oscillators and the reduction of phase noise under locked condition. A graphical interpretation of Adler´s equation predicts the behavior of injection-pulled oscillators in time and frequency domains. An identity derived from the phase and envelope equations expresses the required oscillator nonlinearity across the lock range.
