摘要

采用0.25 μ m CMOS技术，为超高频(UHF)射频识别(RFID)阅读器应用制造了900 mhz线性功率放大器。输出匹配网络采用片上传输在线变压器。输入和级间匹配元件以及射频扼流圈完全集成在设计的放大器中，因此不需要外部元件。该功率放大器在920mhz时提供27 dBm的线性输出功率，采用2.5 v电源。在1db增益压缩点(P1dB)的功率附加效率(PAE)为28%。整个UHF RFID频段(覆盖860兆赫到960兆赫)的增益平坦度为1 dB

A fully-integrated 900-MHz CMOS power amplifier for mobile RFID reader applications

A 900-MHz linear power amplifier has been fabricated for ultra-high-frequency (UHF) radio frequency identification (RFID) reader applications using a 0.25-mum CMOS technology. An on-chip transmission-line transformer is used for output matching network. Input and inter-stage matching components, and RF chokes are fully integrated in the designed amplifier so that no external components are required. The power amplifier provides linear output power of 27 dBm at 920 MHz with a 2.5-V supply. Power-added-efficiency (PAE) at 1-dB-gain-compression point (P1dB) is 28 %. Gain flatness over the full UHF RFID band, which covers from 860 MHz to 960 MHz, is 1 dB
