Ultra-widwband CMOS Low Noise Amplifier [PDF]
, 2007 近年來，自從美國聯邦電信委員會(FCC)將頻譜上 3.1GHz 到 10.6GHz 的頻段分配給 UWB無線通訊系統後，UWB 無線系統的發展受到學術界與工業界的高度關注。UWB 系統是一種低耗電、高傳輸速率的無線通訊技術，其應用領域很廣，包括影像系統、穿透牆壁或地面的雷達顯像、追蹤與監視裝置、以及商業上與家庭娛樂的無線高速傳輸系統等等。而位在 UWB 接收系統的第一級電路，就是低雜訊放大器，由於低雜訊放大器是接收系統的第一級，所以在操作頻率範圍內必須具有很小的雜訊指數(大約3dB)並且要提供夠大的增益(

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.
