Description
  • Tento článek popisuje optimalizaci obvodu se spínanými proudy, použitého pro realizaci dolní propusti. Optimalizace využívá diferenciální evoluci - jeden z evolučních algoritmů. Optimalizace zohledňuje tři požadavky, tudíž se jedná o multikriteriální optimalizaci. Prvním požadavkem je odstranění vlivu neidealit v obvodu na jeho modulovou kmitočtovou charakteristiku. Neidealitami jsou nenulová výstupní vodivost polem řízených tranzistorů pracujících jako proudové zdroje a nenulový odpor spínačů v sepnutém stavu. Druhá a třetí skutečnost respektovaná optimalizací se týká hodnot transkonduktancí tranzistorů v obvodu. Poměr mezi nejvyšší a nejnižší a jejich součet by měl být co nejmenší. Důvodem je lepší návrh obvodu. Cílem optimalizace je získat vhodné hodnoty transkonduktancí vyhovující těmto třem požadavkům. (cs)
  • This paper describes the optimization of a switched-current circuit applied to low-pass filter realization. The optimization uses the differential evolution - one of evolutionary algorithms. The optimization takes into account three requirements, so it is multi-objective optimization. The first requirement is the elimination of the effect of nonidealities in the circuit on its magnitude frequency response. The nonidealities are the nonzero output conductance of the field-effect transistors realizing the current sources and nonzero switch on-state resistance. The second and third fact respected by the optimization is concerned with the values of transconductances of the transistors in the circuit. The ratio between the highest and lowest one and their sum should be as small as possible. The reason is a better circuit design. The aim of the optimization is to obtain suitable values of the transconductances satisfying the three requirements.
