BIOGRAPHY
received his B.S. degree in Microelectronics from Peking University in 2011. He finished his undergraduate thesis in MEMS Lab at UC Davis as an exchange student. He joined MEMS Lab in the same year under the supervision of Prof. Horsley. He is currently pursuing his PhD at UC Davis.

MEMS Electronic Compass: Three-Axis Magnetometer [BPN599]
The goal of this is 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 5 mW/axis with DC power
supply of 3.3V. To enable co-integration with a 3-axis accelerometer, we seek to optimize sensor
performance without the need for a vacuum seal. 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 and develop self-oscillation loops to excite the
sensor at its natural frequency.
