A World-Band Triple-Mode 802.11a/b/g SOC in 130-nm CMOS

A fully integrated system-on-a-chip (SOC) in 130-nm CMOS technology compliant with world-band 802.11a/b/g is presented. This SOC integrates all blocks including 2.4-GHz/5-GHz RF tranceiver, baseband physical layer (PHY), and the medium access controller (MAC). At 1.8 V, the whole SOC dissipates 144/168 mA in receiving mode and 114/150 mA in transmitting mode for 2.4-GHz/5-GHz-band operations. The measured receiver sensitivity at 2.4 GHz/5 GHz is -77.5/-74 dBm at 54 Mb/s rate, and the transmitter EVM at 54 Mb/s rate is -33/-30 dB at an output power of -7/-8 dBm. By integrating multiple on-chip LDOs with no off-chip capacitors, this SOC features the capability of being directly supplied by off-chip switching-type DC/DC converter without performance degradation.
