Abstract
The frequency and current fluctuations, and their correlation were measured in a phase shift transistor oscillator. The spectra are of 1/f type and both are correlated. A demonstration was carried out to reduce the frequency fluctuation, and a useful method to reduce the fluctuation is proposed in an oscillator.
