- W2082020954 abstract "This paper presents a wideband CMOS power amplifier intended for cellular handset applications. The circuit exploits injection locking to achieve a power gain of 20.5dB from a single stage amplifier. The maximum output power of 29dBm, with a peak drain- and power-added-efficiency (PAE) of 66% and 64%, respectively, occurs at a center frequency of 2GHz with a 3V supply. A cross-coupled cascode topology enables a wideband PAE exceeding 50% from 1.6 to 2.6GHz. For output power levels below 4dBm the circuit operates as a linear class AB amplifier with a power consumption of 17mW from a 0.48V supply. The power gain of 20.5dB is kept constant for all output powers; with an AM-AM- and AM-PM-conversion of 0.2dB and 17deg, respectively, over the entire WCDMA dynamic range of 80dB. The circuit is implemented in a standard 65nm CMOS process with a total chip area of 0.52×0.48mm <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> including pads." @default.
