This article presents a multi-input single-output (MISO) electronically controllable current-mode universal biquadratic filter. The proposed circuit is a simple construction consisting of a single multiple-output current-controlled current conveyor transconductance amplifier (MO-CCCCTA), one resistor, and two grounded capacitors, which is well suited for integrated circuit fabrication. The highlight of the circuit is the response of five functions, including high-pass (HP), band-pass (BP), low-pass (LP), band-reject (BR), and all-pass (AP), which can be configured by correctly selecting input signals. In addition, the pole frequency can be independently adjusted from the quality factor by a bias current. Moreover, it is also convenient to be connected in current-mode due to its high-impedance output. The results of the simulation with the Pspice program to test the performance of the proposed universal filter circuit using an internal structure of MO-CCCCTA, BJT construction, were consistent with the theory as expected.

W artykule przedstawiono wielowejściowy jednowyjściowy (MISO) elektronicznie sterowany uniwersalny dwukwadratowy filtr w trybie prądowym. Proponowany obwód jest prostą konstrukcją składającą się z pojedynczego, wielowyjściowego, sterowanego prądowo wzmacniacza transkonduktancyjnego (MO-CCCCTA), jednego rezystora i dwóch uziemionych kondensatorów, co doskonale nadaje się do wytwarzania układów scalonych. Najważniejszym punktem obwodu jest odpowiedź pięciu funkcji, w tym górnoprzepustowy (HP), pasmowoprzepustowy (BP), dolnoprzepustowy (LP), pasmowy odrzucający (BR) i wszechprzepustowy (AP), które można skonfigurować poprzez prawidłowy wybór sygnałów wejściowych. Ponadto częstotliwość biegunów może być niezależnie regulowana od współczynnika jakości za pomocą prądu polaryzacji. Co więcej, można go również wygodnie podłączyć w trybie prądowym ze względu na wyjście o wysokiej impedancji. Wyniki symulacji za pomocą programu Pspice do testowania wydajności proponowanego obwodu filtra uniwersalnego z wykorzystaniem wewnętrznej struktury MO-CCCCTA, konstrukcja BJT, były zgodne z oczekiwaną teorią.
