60 GHz CMOS radio for Gb/s wireless LAN

Abstract

Absrraef-Availability of I GHz of unlicensed speetrum in the 60 GHz band motivates the design of a low-cost 60 GHz wireless LAN (WLAN) system. System and circuit barriers to a low cost implementation are discussed and various solutions are proposed.

Trend on Silicon Technologies for Millimetre-Wave Applications up to 220 GHz

“…Through careful optimization and modelling rules for active and passive components, a standard 0.13 µm CMOS process was proved to be capable of 60 GHz operation despite the related low Ft/Fmax which was in the order of 100 GHz (Doan et al, 2004). Measurements of 65-nm CMOS technology demonstrate Ft of 220 GHz and Fmax of 240 GHz (Fig.…”

A 60GHz, 13 dBm fully integrated 65nm RF-CMOS power amplifier

“…Compared to the general purpose (GP) transistors, LP transistors benefit from a smaller leakage current and a higher supply voltage (1.2V). They unfortunately have a lower tranconductance [4].…”

“…In the ISM band, a 7GHz unlicensed bandwidth around 60GHz is employed [1] [2] [3] [4]. Communications systems are able to ensure 1-3 GBit/s for directional links using an ASK, PSK modulation, or using an Omni-directional link with OFDM modulation with a rate higher than 500Mbps [5].…”

A 14.3% PAE parallel class-A and AB 60GHz CMOS PA

“…The merits of low cost compared to other technology such as GaAs and SiGe, and high integration of CMOS process make it a good candidate for the 60 GHz applications [1]. As the most difficult part, design of high linearity and high efficiency power amplifier (PA) is a real challenge, especially at mm-wave frequency.…”
