摘要

针对802.11ad应用，基于10GSample/s RF-DAC的极性TX实现了30dB以上的混叠衰减和超过3GHz的输入带宽，过采样因子为6倍。当Psat为10.8dBm时，PA漏极效率为29.8%。在3.3Gb/s数据和-23.6dB EVM的QPSK下，平均TX输出功率为5.3dBm, PA效率为15.3%。对应的16-QAM值为:6.7Gb/s时3.6dBm占11.6%，EVM为-18.1dB。40nm块体cmos的0.18mm2 TX核心在0.9V下消耗40.2mW。

A 6x-oversampling 10GS/s 60GHz polar transmitter with 15.3% average PA efficiency in 40nm CMOS

A polar TX based on a 10GSample/s RF-DAC aimed at 802.11ad applications realizes more than 30dB alias attenuation and exceeds 3GHz input bandwidth with 6x oversampling factor. The PA drain efficiency is 29.8% with a Psat of 10.8dBm. Average TX output power is 5.3dBm with 15.3% PA efficiency running QPSK at 3.3Gb/s datarate and -23.6dB EVM. Corresponding 16-QAM values are: 3.6dBm with 11.6% at 6.7Gb/s and -18.1dB EVM. The 0.18mm2 TX core in 40nm bulk-CMOS consumes 40.2mW from 0.9V.
