The impact of inertial thermal feedback, which occurs owing to transistor electrophysical parameters temperature dependence, on transistor oscillator with self-bias noise characteristics is theoretically analyzed. The main attention focuses on the single-circuit quasi-harmonic signal oscillators using bipolar junction transistors. The oscillator CAD model is based on the system of Evtyanov-s symbolic shortened differential equations in a fixed-frequency approximation. Conditions for appearing of the device-s sharp amplitude and phase noise degradation caused by temperature dynamics are revealed.
