Ultra-Low-Power Circuit Design Driving Biomedical Innovations



Building integrated circuits (IC) that operates with ultra-low power (ULP) enables intelligent data acquisition and processing to happen in places where available power is extremely limited. Such scenarios range from the widely known IoT concept, where battery life needs to be extended to ensure low-cost operation, to novel biomedical sensor platforms that operate fully on harvested power. However, a system consumes nW to pW of power requires all its components to function within the power budget, creating many challenges and opportunities in the field of circuit design.

This talk will first cover our latest attempts in exploring the ULP circuit designs targeting nW-level IoT sensor nodes. Specific circuit building blocks include chemical sensor frontends, memories, and crystal oscillators. Key optimization approaches will be described. Next, the talk will discuss a novel implantable sensor platform enabled by ULP circuit design, that allows data transmission native to medical B-mode ultrasound, which leads to the prototype named augmented ultrasonography. The talk concludes with an outlook for ULP circuits in the future.



ZHANG Yihan received the B.Eng. degree in microelectronics from Tsinghua University, Beijing China, in 2013, the M.S. degree in mechanical engineering from Columbia University, NY, USA in 2014, and the Ph.D. degree in electrical engineering from Columbia University, NY, USA, in 2020. He is currently an Assistant Professor at The Hong Kong University of Science and Technology, Hong Kong SAR, China.


His work focuses on integrated circuit design for miniaturized and ultra-low-power (pW-to-nW regime) systems for IoT and biomedical applications. His research has been published in various journals, including Nature Communications, PNAS, JSSC, as well as top-tier circuit conferences including ISSCC, VLSI, and CICC.
