摘要

本文介绍了采用基于开关电容(SC)的单电感多输出(SIMO) DC-DC转换器的全集成2x2 MIMO双带CMOS功率放大器，该放大器采用同步多PA电源电压调制技术。对于802.11ax MCS11 160/40MHz信号，采用本文提出的电源调制方案设计的A/ g波段CMOS放大器在15.7/18.5dBm输出功率下实现-40dB EVM，与3.3V固定电源电压放大器相比，分别节省340/334mW直流功耗。

Fully Integrated 2x2 MIMO Real Simultaneous Dual Band WiFi CMOS Power Amplifiers With a Single Inductor Multiple Output Supply Modulation Technique

This paper presents fully integrated 2x2 MIMO dual-band CMOS power amplifiers with a simultaneous multiple PA supply voltage modulation technique using a switched-capacitor (SC)-based single inductor multiple output (SIMO) DC-DC converter. For 802.11ax MCS11 160/40MHz signals, the designed A/G-band CMOS PAs using the proposed supply modulation scheme achieve -40dB EVM at 15.7/18.5dBm output power and save 340/334mW of dc power consumption compared to 3.3V fixed supply voltage PA, respectively.
