Design and implementation of an IEEE 802.11 baseband OFDM transceiver in 0.18 mu m CMOS

An SISO IEEE 802.11 baseband OFDM transceiver ASIC is implemented. The chip can support all of the SISO IEEE 802.11 work modes by optimizing the key module and sharing the module between the transmitter and receiver. The area and power are decreased greatly compared with other designs. The baseband prototype has been verified under the WLAN baseband test equipment and through transferring the video. The 0.18 mu m 1P/6M CMOS technology layout is finished and the chip is fabricated in SMIC, which occupies a 2.6 x 2.6 mm(2) area and consumes 83 mW under typical work modes.
