Research Focus

Research at SoC Lab lies at the interface of devices, circuits, and algorithms spanning EE, CS, and Physics with applications to wireless communications, IoTs, and more recently cryoelectronic sensing. Our research has demonstrated a wide spectrum of communication circuits and systems motivated by the goal to push the analog-digital interface closer to the antenna and use of digital-intensive architectures through software-defined radios, wideband data converters, ultra-low-power readout interfaces, multi-antenna transceivers, and hardware-software co-design leveraging signal processing and machine-learning constructs. The multi-functional nature of circuits and systems have not only made them ubiquitous and integral to everyday life, but in the coming future silicon circuits and systems will be used more widely across temperatures ranging from sub-millikelvin to room temperature closely integrated with heterogeneous devices. Our research program focuses on emerging sixth-generation wireless communications research, wideband antenna arrays, integrated cryoelectronics, and energy-efficient circuits and systems with a key emphasis on building closed-loop testbeds to characterize chips for sixth-generation wireless and cryoelectronic applications. Key research areas for the lab:

Large Delay Range-to-Resolution True-Time-Delay for NextGen Phased Antenna Arrays	Fast Beam Training in Analog Arrays
Millimeter-wave Massive MIMO for Gigabit Mobile Access	Optimization of High-Speed Cryogenic Circuits
Inter-satellite Communication CrossLinks for CubeSats	Natural Energy Harvesting Enabled Ultra-Low-Power Circuits and Systems
True-Time-Delay based Random Number Generators	Undergraduate Research on High Accuracy Ultrasound-based Wireless Power Transfer and Localization
