A Low-power signal processing front-end and decoder for UHF passive RFID transponders

In this paper, a low-power signal processing front-end and PIE decoder for use in UHF RFID passive transponders is presented. By merging with the decoder, the clock generator does not need to drive a large loading capacitor. Therefore, its power consumption can be greatly reduced. In addition, the r...

Zusammenfassung:In this paper, a low-power signal processing front-end and PIE decoder for use in UHF RFID passive transponders is presented. By merging with the decoder, the clock generator does not need to drive a large loading capacitor. Therefore, its power consumption can be greatly reduced. In addition, the ring oscillator of the generator was designed for low sensitivity to supply voltage variation and low power consumption. Fabricated in a 0.13-mum CMOS process, the measured power consumption consumes only 850 nW.
