Abstract:

This paper presents a novel approach for the analysis of the nonlinear circuits derived from the modeling of THz frequency multipliers. This method combines the rapidity of the Harmonic Balance technique with the reliability of the Genetic Algorithm. For this reason, it has been used within an fully automatic optimization procedure, which determines the maximum conversion efficiency attainable with a device for a given pump power level, as well as the optimal impedance needed at all the harmonic. As an example, we report the analysis and design of frequency triplers based on Heterostructure Barrier Varactors, and operating at 255 GHz.
