This paper demonstrated the first 2-stage, 2.8 W, 1.8 V, 1.9 GHz fully-integrated distributed active transformer (DAT) power amplifier with 50 Ω input and output matching using 0.18 μm CMOS transistors. It has a small-signal gain of 27 dB. The amplifier provides 2.8 W of power into a 50 Ω load with a PAE of 50%.
