摘要

在系统集成电路上设计了一种用于RFID读写器的CMOS功率放大器，该放大器采用0.18 μ m CMOS工艺实现，包括输出匹配电路。所开发的放大器在900 MHz时效率为27%，在1.8 V电源电压下输出功率为24 dBm。此外，它与屏蔽金属线隔离，并具有ESD保护。此外，它对高电源电压和负载阻抗变化具有鲁棒性。

A CMOS power amplifier for a UHF RFID reader

A CMOS power amplifier for an RFID reader, which is implemented in a 0.18 mum CMOS process, is designed on a system IC, including output matching circuits. The developed amplifier has an efficiency of 27 % at 900 MHz and an output power of 24 dBm with a supply voltage of 1.8 V. In addition, it is isolated with shielding metal lines and is ESD protected. Furthermore, it is robust to high supply voltages and load impedance variations.
