Yang, Y. (author), Huang, Mo (author), Du, S. (author), Martins, Rui P. (author), Lu, Yan (author)High-frequency buck converters need a fast transition of switching nodes (high dv/dt). Such high dv/dt, especially the positive one, can cause malfunction of a conventional pulse-triggered active-coupled (PTAC) level shifter that is used to control the high-side NMOS switch. In this work, we first discuss the dv/dt immunity of conventional PTAC...journal article 2023

(author)It is not practical to obtain a large number of labeled data to train a supervised learning network in tunnel lining nondestructive testing with ground-penetrating radar (GPR). To decrease the dependence of supervised learning on the number of labeled data, an improved self-supervised learning algorithm—self-attention dense contrastive...journal article 2023
