    Abstract

    This paper presents intermittently operating RF frontend for proximity wireless communication with wireless power supply. To realize power scalability of the RF frontend, intermittent operation is performed by switching the bias of the amplifier. Quick startup circuit is proposed to accelerate the charging time to a decoupling capacitor. The fabricated test chip in 65nm CMOS occupies 0.075mm<sup>2</sup>. The 3dB bandwidth of amplifier ranges from 1.8GHz to 7.2GHz and current consumption is 8mA. The startup time of the circuit is 5ns.
