Original Abstract

In this paper, a new circuit solution of analogue pseudo-differential second-order all-pass filter operating in the voltage mode is presented. Pseudo-differential, since both input and output terminals are differential, however, the circuit topology features single-ended structure. As active elements the differential difference current conveyors and second-generation current conveyors are advantageously used. The proposed filter features quality factor control without disturbing the polefrequency using single passive element. The designed circuit is less complex compared to fully-differential solutions by maintaining sufficient common-mode rejection ratio. The behaviour of the filter is described by means of symbolic analysis and also by simulations using the UCC-N1B integrated circuit. Furthermore, the performance of the proposed pseudo- differential filter has been validated by experimental measurements.

V článku je prezentováno nové obvodové řešení analogového pseudo-diferenčního fázovacího článku pracujícícho v napěťovém režimu. Pseudo-diferenčního, protože vstup i výstup jsou diferenční, ale obvodové řešení je nesymetrické. S výhodou jako aktivní prvky byly použity DDCC (Differential Difference Current Conveyor) a proudové konvejory druhé generace. Obvodové řešení dovoluje změnu činitele jakosti pomocí jediného pasivního prvku bez vlivu na kmitočet pólu navržená struktura je méně složitá v porovnání s plně diferenčním řešením při zachování dostatečného potlačení souhlasného signálu. Chování filtru je popsání symbolickou analýzou a také simulacemi použitím integrovaného obvodu UCC-N1B. Dále pak byly vlastnoti pseudo-diferenčního filtru ověřeny experimentálními měřeními.navrhovaných pseudo diferenciál filtru validována v experimentálních měření.
