Abstract
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.
