Non-conventional Electronically Controlled Filters Based on Transformation Cells with OTA and CCII
Result description
This paper describes a high-order electronically controlled filter structure based on transformation cells that employ OTA and CCII+ as active elements. The filter has two outputs, where low-pass and high-pass responses can coexist. The transformation cell forms the basic building block in the design of high-order filters with tunable frequency response. To confirm the theoretical analysis, the results measured for a fourth-order filter with tunable cut-off frequency in the range of 1 kHz to 1 MHz are iincluded.

Netradiční elektronicky řiditelný filtr založený na transformačních buňkách s OTA a CCII
Czech description
Tento článek popisuje strukturu elektronicky řiditelného filtru vyššího řádu založené na transformačních buňkách s aktivními prvky OTA a CCII. Filtr má dva výstupy, kdy dolní a horní propust jsou realizovány. Transformační buňka v návrhu kmitočtového filtru vyššího řádu s nastavitelným mezním kmitočtem představuje základní stavební blok. Pro potvrzení teoretické analýzy jsou uvedeny výsledky měření filtru čtvrtého řádu s nastavitelným mezním kmitočtem v rozsahu od 1 kHz do 1 MHz.
