- W3128933332 abstract "In this paper, we propose an efficiency enhanced CMOS power amplifier (PA) at 28 GHz. This work is the first time using the cross-couple pair (CCP) to be the g <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>m</sub> compensation technique to improve AM-AM distortion at the power stage. In addition, we also use the linearizer and adaptive bias to extend the linear power region and increase back-off efficiency. In order to improved PAE in wide input power range, the adaptive bias, linearizer, and g <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>m</sub> -compensation are used for low/medium/high power regions, respectively. The peak gain is 22.72 dB and 3-dB bandwidth is 5.7 GHz. At P <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>1dB</sub> , the measured output power and PAE are 16.73 dBm and 21.37 %. The measured P <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>sat</sub> and peak PAE are 17.68 dBm and 23.56 %. The measured back-off 6 dB PAE is 10.8 %. The total dc power consumption is only 97 mW for 1.2 V supply voltage. To our best knowledge, this PA has higher gain, better back-off PAE, and outstanding FoM." @default.
