Multifunctional Integrated Circuits & Systems
Research in multifunctional integrated circuits and systems has a tangible impact on our daily lives. Most high-performance electronic devices—computers, smart phones, multimedia, and entertainment devices—are constantly being updated to incorporate the newest technology. ECE researchers are pushing toward the next generation of high-performance computing, exploring microwave and millimeter-wave communications; delving into low-power devices like energy harvesters; and integrating complementary metal-oxide semiconductor (CMOS) technology, emerging nanoelectronic technology, and very-large-scale integrated circuits and systems.

ECE research in very-large-scale integrated (VLSI) circuits and systems involves high-performance computing such as computer-aided design, artificial intelligence, and emerging nanodevices. We have been designing and fabricating analog neural chips for spiking recurrent neural networks, modeling and optimizing 3-D neuromorphic computing integrated circuits, designing and analyzing the energy- efficient circuits for green computing and renewable energy systems, and exploring the application of neuromorphic computing and deep learning to wireless communication and cybersecurity.
Recent ECE research in radio frequency integrated circuits has been exploring terahertz integrated radio and radar systems as they apply to wireless communications, biological and chemical molecule sensing, and safety and security applications. We are also pursuing digitally-enhanced RF design techniques to improve performance, power efficiency, and multi-functionality.
ECE researchers are investigating ways to prolong and source battery life with devices that gather and store the energy generated by everyday occurrences. These energy harvesters are integrated circuits powered by solar energy, thermal energy, vibrations, water flow, and hand cranks. We are also investigating methods to make them more efficient—reducing the power dissipation of energy harvesting circuits while extracting the maximum power from transducers.
