Previous Research (available soon)

Current Projects:

Universal Sensor Interface Circuit: sensor readout and microcontroller interface all on one chip.
This custom designed ASIC provides a microcontroller interface through a standard sensor bus, on-chip storage of on-line programmable sensor readout control data, and an on-chip temperature sensor. The third generation of this sensor interface chip is currently being designed in collaboration with Prof. Navid Yazdi at Arizona State University.

Environmental Monitoring Microsystem: wireless, battery powered, multi-sensor systems.
This microsystem combines an embedded microcontroller, power management circuitry, and wireless communication hardware with a network of MEMS-based sensors for monitoring a variety of environmental parameters. The system features very low power operation for extended lifetime (up to 10 years on one battery pack), multi-chip module packaging for small size (similar to a deck or cards), and advanced in-module sensor calibration and temperature compensation for highly accurate measurement data. This research is based on previous work done by Prof. Mason at the University of Michigan and Canopus Systems Inc.

Low-Power Microcontroller: microcontroller specifically designed for sensing microsystems.
Automated Sensor Compensation Algorithms: methods to improve accuracy and reduce manufacturing cost.
