This paper presented the improvement of the first-order all-pass filter fully-balanced current-turnable with the Caprio technique. The proposed circuit was designed with NPN transistors, a capacitor, and a resistor. The amplitude of the signal can have been directly controlled by adding an external resistor (Ree) and has been tuneable electronically. The circuit has a relatively simple architecture. The Caprio technique can reduce total harmonic distortion (THD) to a low level. The proposed circuits were verified by the SPICE simulation, confirming the theoretical analysis.

W artykule przedstawiono udoskonalenie filtra wszechprzepustowego pierwszego rzędu, w pełni zbalansowanego z obrotnicą prądową z wykorzystaniem techniki Caprio. Proponowany układ został zaprojektowany z wykorzystaniem tranzystorów NPN, kondensatora i rezystora. Amplituda sygnału może być bezpośrednio kontrolowana przez dodanie zewnętrznego rezystora (Ree) i jest dostrajana elektronicznie. Układ ma stosunkowo prostą architekturę. Technika Caprio może zredukować całkowite zniekształcenia harmoniczne (THD) do niskiego poziomu. Zaproponowane obwody zweryfikowano symulacją SPICE, potwierdzając analizę teoretyczną.
