was born in Ankara, Turkey, in 1986. He 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 2008 and 2011, respectively. He is currently working toward the Ph.D. degree in Electrical Engineering and Computer Sciences at UC Berkeley under the supervision of Professor Bernhard E. Boser.
His research interests include analog CMOS IC design, interface and control electronics for MEMS inertial sensors. He was a Research Assistant at the Micro-Electro-Mechanical Systems Research and Applications Center, METU, Turkey between July 2008 and June 2012.
FM Gyroscope [BPN608]
We present a gyroscope operating mode that reduces bias errors and scale factor drift and allows whole angle read-out. The gyroscope proof mass orbits in a circle at its natural frequency. An outside observer rotating under the proof mass then perceives a frequency change. If the observer rotates in the same direction as the orbital spin, the perceived frequency decreases, and in the opposite direction, the frequency increases. The addition of a second gyroscope that spins in the opposite direction enables a differential measurement, reducing temperature sensitivity. The frequency difference is exactly the angular rate; thus, the phase difference is the whole angle. Rate bias errors due to mechanical quadrature and cross-axis damping are periodic on the current angle of the proof mass relative to the sensor frame and are hence averaged out over one cycle. A 3-theta dual ring gyroscope chip with integrated CMOS buffer electronics and an off-chip controller demonstrates the technique.
