Proposal of an RF CMOS Integrated Circuit Topology for Spatial Multiplexing of Local Elements (SMILE)

Abstract

Spatial multiplexing of local elements (SMILE) is a front-end architecture which uses one radio frequency (RF) channel to carry multiplexed information from multiple ones. For this scheme, this paper proposes a fully multiplexing 0.35-μm RF CMOS integrated circuit (IC). The one uses an low noise amplifier (LNA) with four inputs to accomplish the multiplexing. To translate the frequency to the base-band, a double-balanced mixer and a voltage-controlled oscillator (VCO) are used. The presented results are satisfactory, validating the proposed compact design, and showing the viability of this topology for SMILE applications.
