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 inertial sensors, such as
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 100 nT/rt-Hz and power consumption of 0.1 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.
