Inductorless CMOS Low Noise Amplifier for Multiband Application in 0.1–1.2 GHz

A 0.18 μm CMOS low noise amplifier(LNA) by utilizing noise-canceling technique was designed and implemented in this paper. Current-reuse and self-bias techniques were used in the first stage to achieve input matching and reduce power consumption. The core size of the proposed CMOS LNA circuit without inductor was only 128 μm 9226 μm. The measured power gain and noise figure of the proposed LNA were 20.6 and 1.9 dB,respectively. The 3-dB bandwidth covers frequency from 0.1 to 1.2 GHz. When the chip was operated at a supply voltage of 1.8 V, it consumed 25.69 mW. The high performance of the proposed LNA makes it suitable for multistandard low-cost receiver front-ends within the above frequency range.

艺术与光共舞——英国伦敦声米埃尔灯光节

引言 英国伦敦灯光节发源地是英格兰北部一座只有50多万人口的小城杜伦，“卢米埃尔”（Lumiere）在法语中的意思就是光，卢米埃尔杜伦（Lumiere Durham）灯光节从2009年开始在杜伦“亮灯”。2018年1月18日到21日，卢米埃尔灯光艺术节再次成功在伦敦举办，共分布在伦敦6个地区，包括伦敦西区、国王十字街、菲茨罗维亚、南岸以及梅费尔和威斯敏斯特＆维多利亚，短短4晚就吸引了约百万游人前来参观。
