| 英文摘要 | This paper presents a fully integrated cmos analog front end for a passive 900-mhz radio-frequency identification (rfid) transponder. the power supply in this front end is generated from the received rf electromagnetic energy by using an rf-dc voltage rectifier. in order to improve the compatibility with standard cmos technology, schottky diodes in conventional rf-dc rectifiers are replaced by diode-connected mos transistors with zero threshold. meanwhile, theoretical analyses for the proposed rectifier are provided and verified by both simulation and measurement results. the design considerations of the pulsewidth-modulation (pwm) demodulator and the backscatter modulator in the front end are also discussed for low-power applications. the proposed front end is implemented in a 0.35-mu m 2p4m cmos technology. the whole chip occupies a die area of 490 x 780 mu m(2) and consumes only 2.1 mu w in reading mode under a self-generated 1.5-v supply voltage. the measurement results show that the proposed rectifier can properly operate with a - 14.7-dbm input rf power at a power conversion efficiency of 13.0%. in the proposed rfid applications, this sensitivity corresponds to 10.88-m communication distance at 4-w equivalent isotropically radiated power from a reader base station. |
