“…This type of tags uses a battery to supply the tag in an active way, while exploits backscattering mechanism to communicate like a passive tag [12]- [15]. Thus, semi-passive tag enables some tag features without affecting the range of operation and becomes an attractive solution for systems that demand more power [16]- [18]. Semi-passive tags can fulfill the applications for implantable devices.…”

A high sensitivity analog front-end is presented for semi-passive HF RFID tag for implantable devices. The design is compatible with the ISO/IEC 14443 Type-A. A rectifier with high power conversion efficiency is presented to provide stable rectified voltage. Novel tag system architecture with wake-up circuit is proposed to improve the sensitivity. Other Key circuits are studied and designed to make the system work effectively. Simulation results show that the AFE has realized much longer recognition distance than passive tags. Its sensitivity is 5.7 dBm and can work properly when the magnetic field is 0.3A/m. The AFE was fabricated with HHNEC 0.13 1P4M CMOS technology with an area of . The AFE is also measured with FPGA based digital baseband. Measurement results show that the proposed AFE can support the 100% ASK demodulation and a modulation depth of 16.4%. The AFE can also accommodate a data rates from 106 Kbps to 848 Kbps are supported. Its power consumption is as low as 129. 6 . This chip meets the demands of a semi-passive HF RFID tag and has great potential for implantable devices.

“…In fact, only practical analyses of specific topics are available. For example, in [21], [23] the UWB backscattering scheme has been analyzed under simplified assumptions, whereas ad hoc prototypes for specific applications are described in [24]. Some papers address only partially the characteristic implementation problems of such architecture and normally consider single-tag operations [22].…”

International audienceIn the new scenarios foreseen by the Internet of Things, industrial and commercial systems will be required to detect and localize tagged items with high accuracy, as well as to monitor the level of certain parameters of interest through the deployment of wireless sensors. To meet these challenging requirements, the adoption of passive and semi-passive ultra-wideband (UWB) radio-frequency identification (RFID) appears a promising solution which overcomes the limitations of standard Gen.2 ultra-high frequency (UHF) RFID. The design and implementation of such systems pose several practical constraints, impacting the overall network architecture. In this paper, the main issues and challenging aspects for the design of a UWB-RFID network considering architectural and protocol choices are discussed in a unitary framework, and practical solutions, accounting for the presented issues, are proposed. Moreover, the possible integration of UWB-RFID with standard Gen.2 UHF-RFID is proposed as an interesting option, discussing architectural solutions, their advantages and drawbacks
