The 65nm CMOS wireless connectivity SoC which support 802.11 a/b/g/n, BT and NFC is implemented. The SoC cover 13.6MHz band for NFC, 2.4GHz and 5GHz band for BT and 802. 11a/b/g/n. The SoC includes RF Transceiver, Baseband modem for 802.11 a/b/g/n, BT and NFC and ARM9 core with various peripherals. The Soc is fabricated using 65nm CMOS process with 5.5 × 5.5 mm2 die area. The power consumption of 802.11n is about 160mW and 180mW for 2.4GHz receiver mode and transceiver mode except PA respectively and 170mW and 190mW for 5GHz case. The 802.11n maximum throughput is measured to 150Mbps. The 802.11 a/b/g/n receiver noise figure is about 4∼5dB at 2.4∼2.5GHz band and 4.8∼5.7GHz band. The sensitivity is about −88.7dBm at MCS0 mode. The sensitivity of BT is about −94dBm. NFC operation range is up to 3.5cm.
