Frequency-Domain Techniques

The ICESTARS partners AWR-APLAC Corporation, Infineon, Oulu University and NXP aim at developing new frequency-domain algorithms and improving the existing ones to provide RF designers with the most effective simulation tool at millimetre wave frequencies. The Harmonic Balance algorithm in particular will be improved to better scale with system size and to better adapt to the design case and simulation environment. Volterra-type analysis will be used for detailed distortion analysis especially needed to design linear power amplifieres. On the methodological side practises will be developed that enable adaptive selection of optimal algorithms or variants of the existing/developed algorithms.

Objectives

This workpackage aims to develop new and improve the existing frequency-domain algorithms in order to provide RF designers with the most effective simulation tools.

The objectives are
to develop simulation methods and algorithms that have optimal scaling properties with regard to component count, number of frequencies and number of unknowns

to develop practices that enable adaptive selection of optimal algorithms or variants of the existing/developed algorithms

to develop HB diagnostic tools to enable high robustness of frequency-domain RF-simulators

to develop an efficient analysis and dimensioning environment for optimizing the linearity and power efficiency of  RF power amplifiers

to extend and refine the numerical algorithms of the present Volterra-on-HB (VoHB) simulation.
