Bu makalede, translineer devre prensibinin kullanıldığı yeni bir BJT tabanlı AB sınıfı elektronik olarak ayarlanabilen pozitif tip diferansiyel fark akım taşıyıcı (EDDCC+) önerilmektedir. Önerilen EDDCC+'nın mevcut akım kazancı elektronik olarak ayarlanabilmektedir. Elektronik olarak ayarlama işlemi translineer çevrimde bulunan akım kaynakları ile sağlanmaktadır. EDDCC+'nın işlevselliğini göstermek için daha önce yayınlanmış bir KHN filtresinin uygulama örneği olarak kullanılmıştır. Benzetimler SPICE programı aracılığıyla yapılmıştır. AT&T CBIC-R (N-2X ve P-2X) transistör modeli parametreler önerilen BJT tabanlı EDDCC+’nın benzetiminde kullanılmıştır. Teorik hesaplamalar, KHN süzgecinin benzetim sonuçları ile doğrulanmıştır. Elektronik olarak KHN süzgeç devresinde bulunan alçak geçiren, yüksek geçiren ve bant geçiren süzgeçlerin kesim frekansı değiştirilmiştir.

Desing of class AB EDDCC+ with the feature of electronic tunability

Öz

In this paper, a novel BJT-based class AB electronically tunable plus-type differential difference current conveyor (EDDCC+) is proposed, in which a translinear circuit principle is utilized. The current gain of the proposed EDDCC+ can be easily adjusted externally. Electronically tunability is provided by current sources in the translinear loop. The proposed EDDCC+ is simulated through the SPICE program to indicate the functionality of the proposed EDDCC+, where a previously published KHN filter is used as an application example. AT&T CBIC-R (N-2X and
P-2X) transistor model parameters are used in the simulation of this circuit. Simulation results of the KHN filter verify theoretical calculations. The cut-off frequency of the low-pass, high-pass, and band-pass filters in the KHN filter circuit has been electronically changed.
