摘要

采用0.13 μm工艺实现了适用于IEEE 802.11 b/g应用的CMOS线性PA，包括所有匹配网络。为了实现高线性输出功率和高效率，提出了一种自适应功率电池(APC)方案，并将其应用于放大器中，该方案对evm为-25(-28)dB的802.11g调制信号输出功率为20.5 (19.5)dBm, PAE为20.2(17.5)%。

A WLAN RF CMOS PA with adaptive power cells

A CMOS linear PA for IEEE 802.11 b/g applications is implemented in a 0.13 μm process including all matching networks. An adaptive power cell (APC) scheme is proposed to achieve high linear output power and efficiency and applied to the PA, which delivers the output power of 20.5 (19.5) dBm with the PAE of 20.2(17.5)% for an 802.11g modulated signal with the EVMs at -25(-28) dB.
