Someya, T. (author), Van Hoek, Vincent (author), Angevare, J. (author), Pan, S. (author), Makinwa, K.A.A. (author)This letter describes an NPN-based temperature sensor that achieves a 1-point trimmed inaccuracy of ±0.15 °C (3σ) from -15 to 85 °C while dissipating only 210 nW. It uses a dual-mode frontend to roughly halve the power consumption of conventional frontends. First, two NPNs are used to generate a well-defined PTAT bias current, then this...journal article 2022

Gu, D. (author), Pan, Jinlong (author), Lukovic, M. (author), He, Jixuan (author)Application of fiber-reinforced polymer (FRP) reinforcement in concrete beams may cause large deflection and crack width, as well as low shear capacity and ductility due to relatively small stiffness of FRP materials. To avoid these unfavorable factors and evaluate the shear behavior of FRP-reinforced structural members, a high-performance...journal article 2022

Pan, K. (author), Palensky, P. (author), Mohajerin Esfahani, P. (author)The main objective of this article is to develop scalable dynamic anomaly detectors with high-fidelity simulators of power systems. On the one hand, models in high-fidelity simulators are typically 'intractable' if one opts to describe them in a mathematical formulation in order to apply existing model-based approaches from the anomaly...journal article 2022

Zhou, Yujue (author), Zheng, Yonglai (author), Liu, Yongcheng (author), Pan, Tanbo (author), Zhou, Y. (author)Vibration-based structural damage detection (SDD) has been a subject of intense research in structural health monitoring (SHM) for large civil engineering structures over the decades. The performance of the conventional SDD approaches predominantly relies on the rational choices of the damage feature and classifier. Hand-crafted features or...journal article 2022

Someya, T. (author), Van Hoek, Vincent (author), Angevare, J. (author), Pan, S. (author), Makinwa, K.A.A. (author)This paper presents a 210nW BJT-based temperature sensor that achieves an inaccuracy of ±0.15°C (3s) from -15°C to 85°C. A dual-mode front-end (FE), which combines a bias circuit and a BJT core, halves the power needed to generate well-defined CTAT (VBE) and PTAT (?VBE) voltages. The use of a tracking ?S ADC reduces FE signal swing and...conference paper 2022

Zhou, H. (author), Chahine, I. (author), Zheng, Wei Xing (author), Pan, W. (author)This paper proposes a sparse Bayesian treatment of deep neural networks (DNNs) for system identification. Although DNNs show impressive approximation ability in various fields, several challenges still exist for system identification problems. First, DNNs are known to be too complex that they can easily overfit the training data. Second, the...journal article 2022
