Project is focused on analysis, minimization and possible elimination of specific sources of randomness and malfunctions in process of contemporary nano-scale IC design of the radio-frequency subsystems. In first-place effects of non-ideal properties of active elements and parasitic features extracted directly from layout design are considered. Randomness in system parameters are described by stochastic differential-algebraic equations and analyzed by using non-monte-carlo methods, i.e. without generation of population of the solutions. Project admits existence of chaotic attractors as solution of the integrated systems.

Description in Czech
Projekt je zaměřen na analýzu, minimalizaci a případnou eliminaci specifických zdrojů neurčitostí a dysfunkcí přímo v procesu návrhu integrovaných radiofrekvenčních subsystémů při použití současných IC technologií. V prvé řadě se jedná o vliv neideálních vlastností použitých aktivních prvků a parazitních reaktančních prvků extrahovaných přímo z navrženého layoutu obvodu. Nahodilosti v hodnotách prvků systému jsou popsány stochastickými algebro-diferenciálními rovnicemi a analyzovány pomocí metod, které nejsou založeny na generaci populace řešení. Projekt připouští existenci chaotických atraktorů jako řešení integrovaných systémů.
