Two topologies of minimum component single input multiple output (SIMO) filters are designed by employing a versatile active building block (ABB), the current conveyor transconductance amplifier (CCTA). The proposed filters work in current mode (CM) and trans-admittance mode (TAM). The CM SIMO filter is designed using two CCTA and two grounded capacitors. The CM filter can be converted to TAM filter just by adding a grounded resistor without any change in the topology. There is no need of passive component matching, and the filters provide all the five responses namely, high-pass (HP), band-pass (BP), low-pass (LP), all-pass (AP), and band-stop (BS) simultaneously. In addition, it provides an independent electronic tunability of angular frequency (ω) and quality factor (Q). The active and passive sensitivities of the filter parameters are low. In CM mode the filter offers low input impedances and high output impedances and in TAM mode the filter offers high input impedance and hight output impedance that support the cascadeability. The CM and TAM filters are designed for a frequency 16.23MHz and the simulation results employing 0.18 µm CMOS technology parameters at a supply voltage of ±1.25 V are obtained using Cadence software to validate the proposed design. Also, the proposed CM SIMO universal filter has been implemented in hardware to confirm its practicality. The commercially available integrated circuits (ICs), the current feedback operational amplifier (AD844) and operational transconductance amplifier (CA3080) and employed for the experimental validation.

Zaprojektowano dwie topologie filtrów z pojedynczym wejściem i wieloma wyjściami (SIMO) o minimalnej składowej, wykorzystując wszechstronny aktywny blok konstrukcyjny (ABB), wzmacniacz transkonduktancji przenośnika prądu (CCTA). Zaproponowane filtry pracują w trybie prądowym (CM) oraz transadmitancyjnym (TAM). Filtr CM SIMO został zaprojektowany z wykorzystaniem dwóch kondensatorów CCTA i dwóch uziemionych kondensatorów. Filtr CM można przekształcić w filtr TAM po prostu dodając uziemiony rezystor bez żadnych zmian w topologii. Nie ma potrzeby dopasowywania komponentów pasywnych i zapewnia wszystkie pięć odpowiedzi: górnoprzepustowy (HP), środkowoprzepustowy (BP), dolnoprzepustowy (LP), all-pass (AP) i band-stop (BS) ) odpowiedzi jednocześnie. Ponadto zapewnia niezależną elektroniczną regulację częstotliwości kątowej (ω) i współczynnika jakości (Q). Aktywna i pasywna czułość parametrów filtra jest niska. W trybie CM filtr oferuje niską impedancję wejściową i wysoką impedancję wyjściową, aw trybie TAM filtr oferuje wysoką impedancję wejściową i wysoką impedancję wyjściową, które wspierają kaskadowość. Filtry CM i TAM zaprojektowano dla częstotliwości 16,23 MHz, a wyniki symulacji wykorzystujące parametry technologii CMOS 0,18 µm przy napięciu zasilania ±1,25 V uzyskano za pomocą oprogramowania Cadence w celu walidacji proponowanego projektu. Również proponowany filtr uniwersalny CM SIMO został zaimplementowany sprzętowo w celu potwierdzenia jego praktyczności. Dostępne na rynku układy scalone (IC), wzmacniacz operacyjny ze sprzężeniem zwrotnym prądu (AD844) i operacyjny wzmacniacz transkonduktancyjny (CA3080) zostały wykorzystane do walidacji eksperymentalnej.
