Sinh-ortam süzgeçlerinin biyomedikal uygulama örneklerinin incelenmesi

Öz

Bu çalışmada sinh-ortam süzgeçlerinin biyomedikal uygulama örneklerinin bir incelemesi sunulmaktadır. Gelişmiş ülkelerde yaşam standartlarının artması, düşük maliyetli ve pratik sağlık çözümleri ihtiyaçlarının bir araya gelmesi biyomedikal sistemlerin ilerleme hızını belirlemektedir. Günümüz biyomedikal sistemlerinin tasarım stratejileri, daha yüksek hız ve geniş dinamik aralık elde etmeye, daha düşük güç tüketimine ve taşınabilir tasarım sağlamaya yöneliktir. Bu nedenle, düşük besleme gerilimde geniş bir dinamik aralık sunma, doğrusallık ve düşük güç tüketimi sağlama, frekans karakteristiğinin elektronik olarak ayarlanması, küçük çip alanı gereksinimi gibi olumlu özelliklere sahip olan sinh-ortam süzgeçleri, son derece düşük güç dağılımı gerektiren biyomedikal uygulamalar için gittikçe önem kazanmaktadır. Elektroensefalogram (EEG), Elektrokardiyogram (EKG) ve Elektromiyogram (EMG) gibi düşük voltaj büyüklüğüne ve düşük frekansa sahip ana biyomedikal sinyallerin alınması sırasında bazı istenmeyen sinyaller oluşmaktadır. Bu istenmeyen sinyallerin biyopotansiyel sinyalden uzaklaştırılması için sinyalin özelliklerine göre çeşitli süzgeçleme işlemleri gerçekleştirilir. Bu çalışmanın konusu, biyomedikal uygulamalar için literatürde önerilen düşük güçlü ve düşük gerilimli sinh-ortam süzgeçlerinin incelenmesidir.
