This paper presents a 71 GHz fully on-chip 3-stage inductor-peaked rectifier in 65-nm CMOS technology. The multistage rectifier is the bottleneck in realizing on-chip wireless power receivers. In this paper, sensitivity and efficiency problems of the mm-wave rectifier are discussed and a 3-stage inductor-peaked rectifier structure is proposed and realized. By cascading inductor-peaked rectifiers with optimized layout, the measured rectifier provide 1 V output voltage with 5 dBm input power at 71 GHz, it also reaches 8% efficiency with 720 µA current load. Compared to previous work of 45 GHz rectifier with 1.2% efficiency [1] and 62 GHz with 7% efficiency [2], this work provides higher efficiency and higher output voltage for mm-wave wireless power receivers.
