The aim towards increasing the patients’ quality of life requires miniaturized and autonomous biopotential monitoring systems. The realization of these systems necessitates the implementation of ultra-low power and high-performance acquisition circuits. This will also provide a means for recently emerging applications of these systems such as gaming, biofeedback, and brain-computer interfaces. Hence, this talk will focus on the development of acquisition circuits for the extraction of the biopotential circuits. Power efficient and high-performance implementations will be discussed. The systems implemented towards the realization of ambulatory biopotential acquisition systems with complete power autonomy will be demonstrated. Finally, future directions and tackles in ambulatory biopotential monitoring will be indicated.
Refet Firat Yazicioglu received the B.S. and the M.S. degrees in Electrical and Electronics Engineering from Middle East Technical University (METU), Ankara, Turkey, in 2001 and 2003, respectively, and the Ph.D. degree in Electronics Eng. from Katholieke Universiteit Leuven, Belgium, in 2008.
From 2003 to 2008, he has been working towards Ph.D. degree with an emphasis on the design of low-power and low-noise readout circuits for portable biopotential acquisition systems. He is currently employed as a researcher by IMEC, Belgium. His research mainly focuses on the design of ultra-low-power and high performance circuits for biomedical applications.
