A low-voltage and low-control-loss RF-dc rectifier with high power conversion efficiency (PCE) at 13.56 MHz band is presented in this paper. This is achieved by utilizing novel reducing reverse loss (RRL) techniques to reduce the reverse leakage current loss. Higher output voltage can also be generated by the multistage stacking method with RRL technology. A boost-type front-end converter composed of an RF-dc rectifier with the RRL technique and a boost converter operating in a discontinuous-conduction mode are also proposed. The single-stage, three-stage pump-type RF-dc rectifier and the boost-type front-end rectifier have been implemented in TSMC 0.18 mu m 1P6M technology. Experimental results show that the maximum PCE of the single-stage and three-stage pump-type RF-dc active rectifiers are 68.6% and 67.9% with input powers of 4.9 and 12.8 dB m, respectively. The maximum PCE of the boost-type front-end converter is 41.3% with 1.2 dB m input power.
