Recently, Ultra-Wide Band (UWB) technology has gradually become the focus of research in the wireless communication field. It is regarded as one of the key technologies of the next generation wireless communication system. FCC passed the UWB commercialization specification on February 14, 2002, the world’s first, allowing the use of low-power UWB systems in the 3.1 GHz to 10.6 GHz frequency band. UWB has more bandwidth than other wireless technologies that can be used, and at the same time it won’t seriously interfere with other wireless communication systems located in the same frequency band. In terms of transmission speed, UWB transmission speed exceeds 100Mbps, even up to 480Mbps, covering a distance of about 10 meters, which is quite suitable for high-end audiovisual multimedia transmission applications. The ultra-wideband wireless communication system operates on a very wide frequency band, which is a considerable test for the design of radio frequency integrated circuits. Roughly speaking, the operation of radio frequency integrated circuits can be divided into transmission and reception aspects. For radio frequency integrated circuits, transceivers, there are mainly several key sub-circuits including low noise amplifiers, mixers, power amplifiers, and phase lock-in loops. With the advancement of CMOS process technology, CMOS can already meet the requirements of high-frequency electrical components, but to achieve broadband characteristics and system specifications at the same time, that is the main challenge of the current design. This article will focus on the ultra-wideband low-noise amplifier part, and make an in-depth discussion on broadband and other characteristics
