Abstract :
A fully CMOS integrated RF transceiver for 802.11b wireless LAN application is implemented and measured. The IC is fabricated in a 0.25 μm CMOS process and packaged in a TQFP package. The single chip transceiver incorporates an I/Q modulator and demodulator, an integrated IF and RF synthesizer with on-chip VCOs, an on-chip LNA, and PA pre-driver amplifier. The chip fully complies with the IEEE 802.11b WLAN standard. The transmitter achieves less than 7.5% EVM and the receiver sensitivity is -86 dBm for 11 Mbps mode. The chip uses 3 V power supply and the current consumption is 60 mA for receiver and 70 mA for transmitter.
