Title: Single CDBA-Based Multifunction Filter Design

Abstract: In this study, we proposed a second-order multifunction filter topology based on a current differencing buffered amplifier. With the proposed topology, five filter functions can be realized. Sensitivity and non-ideal state analyses of the proposed circuit have been performed. In addition to the proposed second-order multifunction filter topology, the third-order quadrature oscillator circuit was operated as the application circuit. In both circuits, the theoretical work and simulation results are in compliance. The proposed design has potential in the medical device design field.

Özet: Bu çalışmada, akım farkı tamponlu yükselticiye dayalı ikinci dereceden çok işlevli bir filtre topolojisi önerilmiştir. Önerilen topoloji ile beş filtre fonksiyonu gerçekleştirilebilir. Önerilen devrenin hassasiyet ve ideal olmayan durum analizleri yapılmıştır. Önerilen ikinci dereceden çok fonksiyonlu filtre topolojisine ek olarak, uygulama devresi olarak üçüncü dereceden dörtlü osilatör devresi çalıştırılmıştır. Her iki devrede de teorik çalışma ve simülasyon sonuçları uyum içindedir. Önerilen tasarım, tıbbi cihaz tasarımı alanında potansiyele sahiptir.
