On the project

Předkládaný projekt navazuje na mezinárodní výzkumné aktivity FEKT VUT v Brně v oblasti návrhu elektronických obvodů s moderními aktivními prvky. Rozšiřuje vědecký projekt GA ČR 102/09/1681 "Automatizování metod syntézy lineárních funkčních bloků a výzkum nových aktivních prvků", řešený na pracovišti navrhovatele o novou oblast nelineárních obvodů. Stále častěji se v literatuře můžeme setkat s novými aktivními prvky vhodnými pro vysokofrekvenční aplikace. Jedná se především o různé typy či modifikace konvejorů, transkonduktančních zesilovačů OTA a jiných proudových aktivních prvků. Tyto obvody pracující v proudovém či smíšeném módu. Aplikační možnosti těchto aktivních prvků jsou pak téměř vždy prezentovány na realizaci kmitočtových filtrů druhého řádu. Cílem předkládaného projektu je analyzovat možnosti využít netradiční aktivní prvky s proudovými vstupními a výstupními branami v oblasti nelineárního zpracování signálů ve vyšších kmitočtových oblastech, než to umožňují řešení s klasickými operačními zesilovači.

Description in English
This project continues in the international research activities of FEEC BUT in the design of electronic circuits with modern active elements. It extends the carrier project GA ČR 102/09/1681 "Computer automatization of methods for linear functional block synthesis and research of new active elements", which is solved at the proposer's workplace, by a new area of nonlinear circuits. More often in the literature we can meet with new active elements suitable for high-frequency applications. Mainly different types or variations of conveyors, transconductance amplifiers OTA, and other current active elements are discussed. These elements work in the current- or mixed-mode and the application possibilities are almost always shown on the design of second-order frequency filters. The aim of this project is to analyze the application possibilities of non-conventional active elements with current input and output ports for non-linear signal processing in higher frequency areas than allowed by solutions using conventional operational amplifiers.
