摘要

提出了一种利用单根控制线实现射频放大器多状态硬件自动调节的方法。介绍了一种门控技术，允许在芯片上实现包络反馈，用于简化电路和获得校准要求。用总面积仅为1.4mm2的GaAs集成电路实现的实验结果表明，该技术具有单芯片集成的潜力。

A Gated Envelope Feedback Technique for Automatic Hardware Conditioning of RFIC PA's at Low Power Levels

A method for automatic multi-state hardware conditioning of RFIC PA's using a single control line is proposed. A gating technique is introduced to allow an on-chip embodiment of envelope feedback, used to simplify circuits and gain calibration requirements. Experimental results obtained with a GaAs IC implementation totaling an area of only 1.4mm2 show a potential for single chip integration of this technique.
