Research

Electronic Textiles (E-Textiles) integrate electronic circuits into textile substrates for applications such as smart wearables. Our work in this area focuses on innovating silicon-level electronics for computing, communication, and power management to enable ultra-compact and unobtrusive form factors.

Our research in energy-efficient design focuses on new architectural techniques and circuit-level innovations to reduce power consumption in integrated circuits and do more work with less energy. Key focus areas for this work include digital circuits and system-on-chips (SoCs), energy harvesting and power-management circuits, on-chip oscillators and sensors (clock sources, temperature sensors, health-monitoring circuits), and static random-access memory (SRAM)

System-on-Chip (SoC) combines broad functionality onto a single silicon chip to enable compact and efficient operation in either general use-cases in the Internet-of-Things (IoT) or specific applications such as health sensing.

Ultra-low-power (ULP) energy-harvesting wearable and implantable sensors can continuously monitor physiological data like heart activity and movement to enable battery-free, real-time healthcare monitoring and early disease detection.

SRAM (Static Random Access Memory) is a key component for building digital circuits and system-on-chips (SoCs). Our work in this area focuses on reducing SRAM power and improving reliability via cutting-edge techniques such as sub-threshold operation, new bitcell designs, and peripheral assist circuits.

Drawing from our expertise in component-level design of circuits such as voltage regulators and SRAM, our work on design automation enables design specifications across a wide tradeoff space to be rapidly translated and optimized to fabrication-ready circuit designs.

Wake-up receivers (WuRXs) offer an energy-efficient means to enable asynchronous wake-up of higher power and higher performance radios without needing frequent (often energy-expensive) synchronization. Our work on WuRXs explores new architectures and circuit-level techniques to reduce power, latency, and improve sensitivity.

Energy harvesting allows electronic devices to harvest, store, and regulate, and operate from ambient energy such as solar, heat, and vibration. Our work in this area focuses on novel circuits and architectures for efficient energy harvesting to enable new applications and allow battery-free operation entirely from harvested energy.
