received the B.S. and M.S. degrees (with high honors) in electrical and electronics engineering from Middle East Technical University (METU), Ankara, Turkey, in 2010 and 2012, respectively. He is currently working toward the Ph.D. degree in electrical and computer engineering at the University of California at Davis, Davis, CA, USA. He was a Research Assistant with the Micro-Electro-Mechanical Systems Research and Applications Center, METU, between 2010 and 2013. He has been a Graduate Research Assistant with the University of California at Davis since 2013. His research interests include MEMS sensors and analog integrated circuits.

MEMS Electronic Compass: Three-Axis Magnetometer [BPN599]
High sensitivity, low cost, low power, and direct integration with MEMS accelerometers and
gyroscopes make the MEMS magnetic sensor a very attractive option in consumer electronic devices. The
goal of this project is to develop a low-power three axis MEMS magnetic sensor suitable for use as an
electronic compass in smart phones and portable electronics. Our objective is to achieve a resolution
of 200 nT/rt-Hz and power consumption of 1 mW/axis with DC power supply of 1.8 V. Although past
devices designed by our group have demonstrated that our resolution goal is reachable, these devices
suffered from dc offset larger than Earth's field and required an external programmable oscillator for
operation. Here, we aim to reduce offset by two orders of magnitude for improving the long-term
stability of the magnetic sensor and to develop self-oscillation loops to excite the sensor either at
resonance or off-resonance.
