Abstract

SMILE (spatial multiplexing of local element) technique is a front-end receiver architecture which uses only one RF channel, carrying multiplexed information from multiple antennas. In this work, a fully integrated LNA (Low Noise Amplifier) in a 0.35 mum CMOS technology with four input channels and multiplex function is presented. The performance characteristics of the LNA such as gain, noise figure, and input impedance are shown in this work. The specifications and performance are in close agreement, validating the proposed compact design.
