Abstract :
A world-band triple-mode SOC compliant with 802.11a/b/g is realized in 0.13 mum CMOS technology. This SOC features multiple integrated capless LDOs to be compatible with DC/DC supply for low current consumption and minimizing external BOMs. With supplying by a DC/DC converter, the measured 2.4 GHz/5 GHz sensitivity is -77.5 dBm/-74 dBm at 54 Mbps, and TX 2.4 GHz/5 GHz 54 Mbps EVM is -32 dB/-30 dB at an output power of -7 dBm/-8 dBm. This SOC consumes 71 mA/83 mA at RX mode and 56 mA/74 mA at TX mode at 2.4 GHz/5 GHz band respectively.
