A high-efficiency CMOS rectifier with low start-up voltage for ultra-high-frequency (UHF) radio-frequency identification (RFID) applications is presented. To enhance the power conversion efficiency (PCE) of the conventional rectifier when the input voltage (power) is low, appropriate gate-drive voltages for each stage of the rectifier are generated using a(More)
A CMOS rectifier with a wide input signal range for radio-frequency identification (RFID) applications is presented. Using quasi-floating gate technique, a gate-biasing scheme is proposed to provide a relatively flat power conversion efficiency (PCE) curve for a wide input voltage (power) range. The proposed technique also enables an efficient operation for(More)
