Abstract (2. Language): 
In this paper, a universal current-mode filter for simultaneously providing all the general responses such as low-pass, band-pass, high-pass, notch and all-pass responses, is proposed. The proposed biquad employs only two grounded capacitors and three identical plus-type current-controlled conveyors (CCCII+s) thus it can easily be realized in integrated circuit (IC) process. Nevertheless, it requires a resistive component matching condition for all-pass response. Also, signal limitation and stability problems in analog filters are discussed. Finally, simulation results with SPICE program are given to confirm the theory.
Abstract (Original Language): 
Bu makalede, alçak-geçiren, bant-geçiren, yüksek-geçiren, bant-söndüren ve faz kaydıran cevaplar gibi genel filtre cevaplarını aynı anda sağlayabilen akım-modlu bir filtre önerilmiştir. Önerilen ikinci derece filtre sadece topraklanmış iki kapasitör ve üç tane benzer artı-tipli kontrollü akım taşıyıcı içerir. Böylece önerilen filtre tümleşik devre (IC) olarak kolaylıkla tasarlanabilir. Fakat, önerilen filtre faz-kaydırımı için bir dirençsel eleman uyumuna ihtiyaç duyar. Ayrıca, analog filtrelerdeki işaret sınırlamaları ve kararlılık problemleri tartışılmıştır. En sonunda, simulasyon sonuçları SPICE program kullanılarak teoriyi sağlamlaştırmak için verilmiştir.
