A Low-Power and Flexible Energy Detection IR-UWB Receiver for RFID and Wireless Sensor Networks

Zhuo Zou, Sarmiento M. David, Peng Wang, Qin Zhou, Jia Mao, Fredrik Jonsson, Hannu Tenhunen, Li-rong Zheng, A Low-Power and Flexible Energy Detection IR-UWB Receiver for RFID and Wireless Sensor Networks. IEEE Transactions on Circuits and Systems 58, 1470-1482, 2011.

Abstract:

This paper presents an energy detection Impulse Radio Ultra-Wideband (IR-UWB) receiver for Radio Frequency Identification (RFID) and Wireless Sensor Networks (WSN) applications. An Application-Specific Integrated Circuit (ASIC) consisting of a 3-5 GHz analog front-end, a timing circuit and a high speed baseband controller is implemented in a 90 nm standard CMOS technology. A Field-Programmable Gate Array (FPGA) is employed as a reconfigurable back-end, enabling adaptive baseband algorithms and ranging estimations. The proposed architecture is featured by high flexibility that adopts a wide range of pulse rate (512 kHz-33 MHz), processing gain (0-18 dB), correlation schemes, synchronization algorithms, and modulation schemes (PPM/OOK). The receiver prototype was fabricated and measured. The power consumption of the ASIC is 16.3 mW at 1 V power supply, which promises a minimal energy consumption of 0.5 nJ/bit. The whole link is evaluated together with a UWB RFID tag. Bit error rate (BER) measurement displays a sensitivity of -79 dBm at 10 Mb/s with 10-3 BER achieved by the proposed receiver, corresponding to an operation distance over 10 meters under the FCC regulation.
