Moein Shayegannia and Hasan Al-Nashash
ABSTRACT: This paper deals with the design of low frequency filter using gyrator for biomedical applications. The dynamic range of filter cut off frequency is between 1HZ to 100 HZ, which coincides with the biomedical constrains. The paper is organized as follows. In section I, an introduction of the biomedical signals, filter considerations and the existing methods for LPF are discussed. In section II, the gyrator and how it is used to simulate a capacitor is introduced. In section III, we present some results of the proposed method. Finally, conclusions and suggestions for future work are included in section IV.
