Abstract :
This paper describes a fully integrated power amplifier working at 60GHz band and implemented in CMOS 65nm technology. The ring topology of a distributed active transformer (DAT) is applied to realize efficient power combination and impedance transformation simultaneously. The design consists of the transformer, active stages, and input power divider, and the matching networks between the components are implemented to form the complete system. The power amplifier achieves a simulated 21.36 dBm output power at 1 dB compression, with 1dB bandwidth of 12.5 GHz. The power added efficiency of total system is 4.56% and the transducer gain is 4.95 dB.
