Mixed-signal MEMS for Sensing Instrument and Biomedical Applications
Thursday, February 18, 2016 - 3:30pm to 4:30pm
Refreshments and discussion following
Presenter: Dongning Zhao
Abstract: In recent years, there has been an increasing demand for state-of-the-art MEMS technology development to address the basic and most important issues for humans: energy, environment, and health. By combining fundamental principles in mechanical engineering, semiconductor fabrication technology, low-noise low-power analog circuitry in MEMS development, a variety of new products have been created to increase the quality of people's lives and improve the efficiency of product manufacturing processes. This talk will discuss on mixed-signal, low-offset interface circuit for MEMS applications. Specially, I will discuss the research and development of a low-noise CMOS Interface for inertial measurement unit (IMU) - micro-g accelerometer featuring high sensitivity and large dynamic range. Also I will discuss the development of a portable multi-channel MEMS ultrasound sensor array for 3-dimensional high-resolution medical imaging applications. The talk will conclude with a brief discussion on future research such as MEMS applications for portable electronics and energy harvesting for IoT / bio-medical sensors.
Dongning Zhao received his BS and MS in Electrical Engineering from the University of Nebraska - Lincoln in 2001 and 2003, respectively. He received his PhD degree in Electrical and Computer Engineering from the Georgia Institute of Technology in 2009. His doctoral dissertation was focused on CMOS low-noise interface circuits design for MEMS accelerometer. From 2011 to 2014, he was with the Institute of Microelectronics (IME) Singapore, as a Scientist, where he worked on the research and development of low-power CMOS analog/power IC system for ultrasound bio-medical imaging applications. Presently he is working on battery power management in the electric charging pile system for green electric cars. His research interests and areas are CMOS analog/power/biomedical IC and system design for MEMS sensors and implantable/wearable medical devices.
