A Low-Power Monolithic CMOS Transceiver for 802.11b Wireless LANs

Wireless LANs (WLANs) are currently seeing significant growth in the worldwide consumer electronics market. The high data rate (11 Mbps) WLAN standard IEEE 802.11b in unlicensed 2.4 GHz ISM band is the most popular one. With more handheld devices such as PDA and IP phones integrated with the WLAN function, the low power design of the wire-less transceiver chip is becoming critically important in order to increase battery life. On the other hand, realizing a high level of integration in low-cost CMOS technology is desirable to reduce the manufacturing cost. A monolithic CMOS 802.11b transceiver with low power consumption is presented in this paper.
