Near Infra-Red Light Detection Using Silicon Avalanche Photodiodes: Design Challenges in Standard CMOS Technology

Ehsan Kamrani: Ehsan received his B.Sc. degree in Biomedical engineering from SBMU, Iran, in 2002 and his Masters degree in Electrical and Control Engineering from TMU, Iran, in 2005. He has been with the Institute of Medical Engineering, Salamat-Pajooh-Bartar (05-09), MetaCo. (03-04), Ferdowsray (00,04), Saadat Co. (98-04) and Imen-Ijaz Inc. (99-00) working on design and development of biomedical imaging and real-time monitoring systems. From 2005 to 2009 he has been an Academic Member-Instructor in the Department of Electrical and Electronics Engineering, University of Lorestan, Iran. His expertises are on Analog integrated circuits, smart CMOS image sensors, wireless networked sensors, web-based control systems and biomedical signal/image processing. He published more than 30 papers in peer reviewed journals and conference proceedings. Since 2009 he has been doing his PhD on Biomedical Engineering at Polystim neurotechnologies Laboratory, Ecole Polytechnique, Montreal, Canada. He is working on design and implementation of an fNIRS photo receiver for real-time brain monitoring. From March 2012 he has joined Harvard Medical School and Wellman Center for Photomedicine, Massachusetts General Hospital in Boston, MA, USA working in an active biooptics project for developing novel innovative technologies by integration of photonics and biological system aiming at developing a novel diagnostic optical instrument for medical applications.
