本文提出一款基于变压器功率合成技术的79GHz功率放大器,采用65nm CMOS工艺实现。在1V供电下达到19.3dBm输出功率,有效解决了毫米波频段高输出功率与低功耗之间的矛盾。
For a highly integrated wireless system including on-chip antennas, high-outputpower power amplifiers (PA) are required to cover the desired transmission range. In order to achieve the output power level, power-combining techniques have gained more attention in recent years [1-5]. An efficient power-combining solution is essential since less DC power is needed for the same level of output power, and the difficulties of thermo-dissipation are thus relieved in a high-output-power PA. Transformer-based power combining is one of the common techniques, which can increase impedance-transformation ratio by increasing the number of input ports and results in a compact layout and reasonable loss [1-3, 5]. However, due to the short wavelength at mm-Wave frequencies, the behavior of a transformer departs far from that of a lumped element. Consequently, transformer combining has its limitations in combining signals arising from
