Abstract :
A stacked amplifier architecture has been used to achieve high RF output power levels in sub-100nm CMOS. The stacking makes it possible to both operate the power amplifier (PA) from a large supply voltage and implement RF power combining. As a proof of concept, a 6.5-GHz PA has been integrated in a 65-nm standard CMOS technology. The amplifier achieves 27.4-dBm output power with an efficiency of 19.2% at 6.5 GHz when driven from a 3.6-V supply voltage and 29.6-dBm output power with an efficiency of 20.3%, when driven from a 4.6-V supply voltage.
