Title:
“Manufacturable 60GHz CMOS LNAs”
Abstract:
Emerging broadband applications are pushing for the need to build high data rate wireless transceivers at 60GHz for high volume low cost mobile devices. Central to the success of implementing such transceivers is the robust design of 60GHz CMOS RF front ends, especially the low noise amplifiers (LNAs). In this talk, two different topologies are used to build LNAs; two-stage CG-CS LNA and three-stage CS LNA. The performance of these topologies is compared to select the best one with the best transmission line type. I then propose a digital self-calibration technique for LNAs’ to enhance the yield to at least 90%. The proposed technique is shown to maintain typical specified performance at worst case corners and hence allowing for manufacturable 60GHz RF CMOS design for high volume applications without leading to over-design or increasing power consumption. The LNA has been designed and simulated in IBM 90nm technology. It is shown that the proposed calibration restores LNA performance in the presence of random process, supply and temperature variations. After presenting simulation results, I will conclude my talk with a small discussion on some of the future challenges and suggestions in designing robust 60 GHz LNAs
