“…The reason is that sinh-domain filters have inherent class-AB operation, which allows biasing at current levels significantly lower than that of the maximum signal that can be handled by the system. In addition, the employment of MOS transistors in the subthreshold region offers the advantage of reduced power consumption [5][6][7]. The topology operates in a 0.5-V supply voltage environment.…”

An ultra-low voltage sixth-order low pass filter topology, suitable for sensing the T-wave signal in an electrocardiogram (ECG), is presented in this paper. This is realized using a cascade connection of second-order building blocks constructed from a sinh-domain two-integrator loop. The performance of the filter has been evaluated using the Cadence Analog Design Environment and the design kit provided by the Austria Mikro Systeme (AMS) 0.35-µm CMOS process. The power consumption of filters was 7.21 nW, while a total harmonic distortion (THD) level of 4% was observed for an input signal of 220 pA. The RMS value of the input referred noise was 0.43 pA, and the simulated value of the dynamic range (DR) was 51.1 dB. A comparison with already published counterparts shows that the proposed topology offers the benefits of 0.5-V supply voltage operation and significantly improved power efficiency.

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.
