An Adaptive Controlled Chip-Level Wireless Power Transfer System with DPID Controller for Wireless 3-D Stacked Chips
2023 China Semiconductor Technology International Conference (CSTIC)(2023)
摘要
In this paper, we presented an adaptive controlled chip-level wireless power transfer (WPT) system with a digital proportional-Integral-derivative (DPID) controller for next generation of high-density wireless three-dimensional (3-D) stacked semiconductor technology. The WPT is designed in UMC 55 nm CMOS process with an area of 0.3 mm
