Abstract :
This paper describes design techniques for RF CMOS receivers operating in the 2.4-GHz band. A direct-conversion receiver targetting spread-spectrum wireless LAN applications employs partial channel selection filtering, DC offset removal and baseband amplification. Fabricated in a 0.6-μm CMOS technology, the receiver achieves a noise figure of 8.3 dB, IP3 of -9 dBm, IP2 of +22 dBm, and voltage gain of 34 dB while dissipating 80 mW from a 3-V supply. Dynamic range and linearity requirements of A/D converters used in RF receivers are also presented
