A 1-5 GHz ultra-wideband CMOS low-noise amplifier (LNA) is presented. A common-gate topology is adopted for the input stage to achieve wideband input matching, while a cascode stage is used as the second stage to provide power gain at high frequencies. By using two inductors in the LNA, a small chip area is obtained. The LNA has been fabricated in a standard 0.18 μm CMOS technology. The measured maximum...
Traditionally, transceivers for wireless communication have to be carefully optimized for a given implementation technology in order to meet design targets. This compromises scalability and analog circuits therefore have to be redesigned when a design is to migrate between technology nodes. The added cost from redesign is not acceptable for low cost applications such as DECT and alternative approaches...
