Devices and Circuits for Semiconductor Magnetic Field Sensors

Silicon Integrated Circuit Technology has become the new driving force in sensors and actuators altering the conventional sensor concepts. With numerous applications of Magnetic Field Sensors in diverse areas from Nuclear processing to automotive and servo systems to magnetic signal/data processing, low-cost portable solid-state Magnetic field sensors are now being regularly developed on standard IC process technologies. A magnetic field sensor converts the presence of a magnetic field into an electronic signal. Semiconductor magnetic field sensors on IC chips usually exploit the Lorentz force on charge carriers. IC technology provide the advantage of having the conditioning and signal processing circuitry on the same chip with the magnetic field sensor with the possibility of monolithic integration with microcontrollers and microprocessors. This special session of Magnetic field Sensors (MFS) solicits papers in recent advances in Integrated Hall plates, Magnetic Field Effect Transistors (MAGFETs), Bipolar Magneto-Transistors, Magneto-Diodes, Magneto-Resistors etc. and related circuit design aspects. Magnetic Field Sensors based on III-V semiconductor materials is also of interest.

Text Box: S. M. Rezaul Hasan received his B.S.E.E. from BUET, Dhaka, his M.S.E.E. from the State University of New York at Buffalo, and his Ph.D. in Electronics Engineering from the University of California Los Angeles (UCLA) . From 1983 to 1986 he was a VLSI design engineer at Xerox Microelectronics Center in El Segundo, California, where he worked in the design of CMOS VLSI microprocessors. In 1986 he moved to the Asia-Pacific region and served several institutions including Nanyang Technological University, Singapore (1986-1988), Curtin University of Technology, Perth, Western Australia (1990-1991) and University Sains Malaysia, Perak, Malaysia (1992-2000). At University Sains Malaysia he held the position of Associate Professor and was the coordinator of the Analog and VLSI research laboratory. He spent the next four years (2000-2004) in United Arab Emirates, where he served as an Associate Professor of Microelectronics and IC design in the Department of Electrical and Computer Engineering at the University of Sharjah. While in Sharjah he received the National Bank of Sharjah Award for outstanding research publication in Integrated Circuit Design. Presently he is the Director of the Center for Research in Analog and VLSI microsystems dEsign (CRAVE) at Massey University, Auckland, New Zealand. He is also a senior lecturer within the School of Engineering and Advanced Technology (SEAT). He has so far published 43 international journal articles and 95 proceedings papers in Integrated Circuit Design, CMOS Sensor Design and VLSI Design. Dr. Hasan has also served as consultant for many electronics companies. His areas of interest include Analog and RF Integrated Circuit and VLSI Micro-system Design, CMOS and MEMS sensor design, and Semiconductor Device Physics. He is an editor of the Hindawi journal of active and passive electronic components. He is a senior member of the IEEE.
