46GHz differential power amplifier with 11GHz bandwidth using on-chip transformer
説明
The millimeter-wave differential power amplifier using on-chip transformer is proposed to achieve high saturated power. To realize the high freqency operation, cross couple capatitor MOSFET is applied. The parasitic element is reduce the performance of the circuit. In this paper on-chip transformer is used as balun and impedance-matching network. The component loss is reduced by unifying the function of two components. Moreover, the layout is optimized to reduce the parasitic element and lead line of the MOSFET. The proposed power amplifier is fablicated using 1P12M 45nm CMOS process. The 46GHz center frequency with 11GHz bandwidth with peak gain of 8.5dB per stage was achieved. The power added efficiency is 18%.
