Öneriler

Yapılan çalışma, ileride yapılacak çalışmalarla transistörlerin ideal olmayan karakteristiklerinden dolayı frekans cevabında oluşan kaymanın düzeltilebilmesi yönünde geliştirilebilir. Bu yöntem kullanılarak farklı filtre yaklaşımlarına sahip ve farklı uygulama alanları için daha yüksek dereceden filtreler tasarlanabilir.

İleride transistör teknolojisindeki gelişmelere paralel olarak da bulunabilecek farklı karakteristikteki transistör tipleri bu çalışmada kullanılarak ideal olmayan transistör özelliklerinin yarı iletken eleman yapısındaki değişiklerle iyileştirilerek, filtrenin çalışma karakteristiği üzerindeki etkileri incelenebilir.
