Abstract
AbstractTo achieve increased output and frequency stability in solid‐state oscillation it is necessary to reduce the oscillator noise. Measures that may be employed to achieve this include operation of a number of oscillators in parallel, external injection locking, self‐injection locked operation or a combination of such measures. The purpose of this paper is to clarify the nature of the mechanism which causes improved stability or improved noise characteristics due to injection‐locked operation and to develop an intuitive grasp of the stability and noise characteristics of such complex oscillator circuits. In the analysis technique we consider oscillators operating above the microwave band using traveling waves. The Rieke diagram of the oscillator is transformed so that the traveling wave analysis can be performed and a graphical presentation is used to show how arbitrary frequency components of noise are outputted. It is clearly shown how the oscillator output signal (angular frequency ω0) interacts parametrically with the noise equivalent input signal (ω0 ‐ ωn) due to the input signal amplitude dependence of the Rieke diagram, producing a noise output signal of angular frequency ω0. We are also able to show on the Rieke diagram how the noise characteristic varies with the magnitude and frequency of the injection signal.
