Original Abstract

Based on the fifth-order voltage-mode low-pass LC ladder structure the active only grounded-C equivalent circuit solutions are presented. As active building blocks the current follower transconductance amplifiers (CFTAs) are used. Using the signal flow graph approach, the initial solution using nine active elements is further optimized to a more simple topology employing only six active elements and five capacitors. Using the readily available UCC-N1B integrated circuit, the performance of the optimized active only grounded-C voltage-mode low-pass filter has been verified both by the simulations and the experimental measurements.

Na základě LC příčkového článku pátého řádu je prezentováno řešení aktivního filtru s uzeměnými kapacitory. Jako aktivní stavební bloky jsou použity CFTA zesilovače. Použitím metody grafů signálových toků je počáteční řešení využívající devíti aktivních prvků dále optimalizováno na jednoduší řešení využívající šest aktivních prvků a pět kapacitorů. Pomocí dostupného integrovaného obvodu UCC-N1B bylo chování optimaliovaného řešení dolní propusti pátého řádu ověřeno jak simulací tak experimentálním měřením.
