Abstract :
This paper describes a method of implementing thermal power feedback (TPF) into a 5th order nonlinear distortion analysis with Volterra-series. The main advantages of the Volterra analysis is that different thermal and electro-thermal contributions of distortion can be separated, giving extensive information about dominant distortion mechanisms. As an example, electro-thermal distortion in a simple common emitter amplifier is studied.
