Abstract

This paper presents a 60 GHz band transformer-based inductor peaked differential rectifier in a 40 nm CMOS technology. The rectifier is used as a wireless power receiver in a monolithic wireless powered IoT transponder. A new transformer-based inductor peaked differential topology is proposed and implemented to improve the sensitivity. In this method, the input transformer performs voltage boosting function, inductor peaking function, and impedance transfer function simultaneously within a compact die size. The proposed rectifier topology achieves an excellent peak sensitivity of -12 dBm at 64 GHz for 1 V output voltage. The overall sensitivity over the entire operational range of 58-64 GHz is below - 5 dBm.
