CMOS RF receiver: from system architecture to circuit implementation

RF-CMOS is considered more favorable primarily for the following two reasons: Firstly, capitalizing on the fabrication maturity and manufacture volume, one would justifiably expect the lowest possible cost. Secondly, it has undoubtedly the best potential for wireless system-on-chip (SOC) for its seamless compatibility with digital baseband circuit fabrication process. This paper reviewed system architectures of receiver design with emphasis on suitability of CMOS implementation. Circuit design issues for various building blocks in a typical receiver have been discussed. Finally, a design example of a 5-GHz receiver for WLAN application has been demonstrated
