A fully integrated SoC for 802.11b in 0.18μm CMOS

Abstract

A 0.18 /spl mu/m CMOS IEEE 802.11b SoC integrated all the radio building blocks including the PA, the PLL loop filter, and the antenna switch, as well as the complete physical layer and the MAC sections. At 2.4 GHz, it dissipates 165 mW in the receive-mode and 360 mW in the transmit-mode from a 1.8 V supply. The receiver achieves a typical NF of 6 dB, and -88 dBm sensitivity at 11 Mbit/s rate. The transmitter delivers a nominal output power of 13 dBm.
