This paper presents a passive UWB-RFID systemwith Time-Difference-of-Arrival (TDOA) positioning from systemto circuit perspectives. Wireless powered RFID tags with UWBtransmitter transmit wideband pulses to readers, allowing highaccurate Time-of-Arrival (TOA) estimation. Low power lowcomplexity TOA estimations using energy detection receiver areinvestigated. Max Energy Select (MES), Threshold Comparison(TC), and MES-Search-Back (MES-SB) algorithms are evaluatedand analyzed. As a special focus, a prototype of the proposedenergy detection receiver is designed and implemented. It consistsof a 3.1-4.8 GHz IR-UWB analog frontend with high speed digitalcircuits in 90 nm CMOS, and a flexible back-end with a TOAestimator on FPGA.
