Current Projects

VLSA (Very Large Scale Analog)

Project Website: www.eecs.umich.edu/vlsa

This project seeks to improve the performance of all-digital implementations through exploration of new system architectures. Moreover, digital design flows such as synthesis and automatic place-and-route are utilized in order to simplify the design process. This ensures that designs are portable as well as take advantage of improvements that process scaling brings

Cubic-mm Sensors

Project Website: cubicmm.eecs.umich.edu

The goal of this program is to develop a sensing platform with transducers (i.e. imaging, temperature sensing), wireless communication, high accuracy timer, processor, memory, battery and energy harvesting, in a 1mm3 volume. In addition, we will assemble and package sensor node platforms and disseminate them to the broader community for trials in a wide range of applications.

60 GHz Front-End in CMOS with On-Chip Antenna for Wireless Sensor Network Applications

Wireless sensor nodes in a sensor network are typically equipped with radio transceiver, microcontroller, and energy source such as battery. The radio front-end dominates the sensor node's size; robust communication distance between nodes and gateway, and lifetime under limited power supply. This project seeks to develop a fully integrated RF front-end circuit for Wireless Sensor Network (WSN) applications. On-chip antennas as well as front-end circuits will be integrated onto the integrated platform with other components such as microprocessor, sensors and batteries to realize a complete wireless sensor node. It aims to communicate with other nodes in a distance of 1000x of its size length under ultra low power consumption.
