Ultra high data rate CMOS FEs

The availability of numerous mm-wave frequency bands for wireless communication has motived the exploration of multi-band and multi-mode integrated components and systems in the main stream CMOS technology. This opportunity has faced the RF designer with the transition between schematic and layout. Modeling the performance of circuits after layout and taking into account the parasitic effects resulting from the layout are two issues that are more important and influential at high frequency design. Performaning measurements using on-wafer probing at 60GHz has its own complexities. The very short wave-length of the signals at mm-wave frequencies makes the measurements very sensitiv to the effective length and bending of the interfaces. This paper presents different 60GHz corner blocks, e.g. Low Noise Amplifier, Zero IF mixer, Phase-Locked Loop, A Dual-Mode Mm-Wave Injection-Locked Frequency Divider and an active transformed power amplifiers implemented in CMOS technologies. These results emphasize the feasibility of the realization 60GHZ integrated components and systems in the main stream CMOS technology.
