Abstract

In analog circuits generally electronical controllability is provided by adjusting current or voltage of the terminal of used active building block through an external source. Voltage differencing current conveyor provides electronical controllability through its transconductance gain. In this study, multi-input multi-output voltage differencing current conveyor based biquadratic filter is proposed. The proposed circuit is designed by using minimum components. It uses only one capacitor and two resistors and one voltage differencing current conveyor. It realizes low-pass, high-pass and band-pass filter functions. TSMC 0.18 μm CMOS process parameters are used to realize voltage differencing current conveyor and investigate the proposed circuit in PSPICE program. It is observed that theoretical analyses and simulation results are closely to each other. Total harmonic distortion analyses are performed to assess the feasibility of the presented circuit.

Özet

Analog devrelerde elektronik olarak ayarlanabilirlik özelliği, genellikle kullanılan aktif devre bloğunun terminallerinden birinin akım veya geriliminin harici bir kaynak kullanılarak ayarlanabilmesi ile sağlanır. Gerilim farkı alan akım taşıyıcı (Voltage Differencing Current Conveyor), geçiş iletkenliği kazancı sayesinde kullanıldığı devreye elektronik olarak ayarlanabilirlik özelliği kazandırır. Bu çalışmada, çok girişli çok çıkışlı (Multi Input Multi Output) gerilim farkı alan akım taşıyıcı tabanlı ikinci dereceden filtre devresi önerilmiştir. Önerilen devre mümkün olan en az sayıda eleman kullanılarak tasarlanmıştır. Önerilen devrede bir direnç, iki kondansatör ve bir gerilim farkı alan akım taşıyıcı elemanı kullanılmıştır. Bu devre alçak geçiren (Low Pass), yüksek geçiren (High Pass) ve bant geçiren (Band Pass) filtre fonksiyonlarını gerçekleştirmektedir. PSPICE benzetim programında gerilim farkı alan akım taşıyıcı bloğu için TSMC 0.18 μm CMOS işlem parametreleri kullanılarak önerilen filtre devresinin çalışması incelenmiştir. Teorik analizler ve PSPICE benzetim sonuçlarının birbirine oldukça yakın olduğu gözlemlenmiştir. Önerilen devrenin uygulanabilirliğini değerlendirmek için Toplam Harmonik Bozulma (Total Harmonic Distortion) analizi yapılmıştır.
