A low-power, reliable and re-configurable clock recovery circuit for UHF RFID transponders for the EPC Class-1 Generation-2 standard is proposed. Based on a digital frequency-locked loop, the clock recovery circuit uses timing information available in the downlink data, namely, the pulse intervals of the PIE-coded data, to calibrate an oscillator's output frequency to meet the stringent frequency...
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...
Conventional Weaver receivers select the signal channel and reject the image. This paper offers a simple method making it possible to select either signal or image by a single LO frequency. As a result, the number of LO frequency locations can be reduced by half, thereby relaxing the RF integer-N PLL frequency synthesizer requirements.
