Analysis of electrothermal transients and digital signal processing in electrically and thermally nonlinear microwave circuits

摘要

The paper introduces a new approach to the analysis of nonlinear circuits containing temperature-dependent devices and excited by slowly modulated microwave carriers. For best accuracy and efficiency, the different dynamics of electrical and thermal phenomena are exploited. The electric circuit is simulated by a sequence of HB analyses of equal size, driven by an exact HB analysis loop for the thermal circuit.
