However, this power consumption ends up being dwarfed by that of its modulating baseband circuitry. Furthermore, they are plagued by short reading ranges. The work reported in this paper demonstrates, for the first time, the use of a combined single-element oscillator/reflection-amplifier architecture. This remarkable system combines two critical features for range extension-the highest reflection-amplification RFID gain of the literature (48 dB) and higher-than-MHz sub-carrier offset frequency-while displaying a power consumption lower than that of any comparable commercial (amplifier-less) oscillator: 20 µW. This is achieved by using a tunnel-diode, whose properties as a baseband-oscillator and a 5.8 GHz reflection-amplifier are analyzed, before both are combined. This highly voltage-sensitive system is synergistically associated with a first-of-a-kind self-regulating tunnel diode-based rectifier to propose a fully-tunnel-diodes-based passive RFID design which could enable the future of practical km-range RFIDs.","PeriodicalId":6784,"journal":{"name":"2020 IEEE/MTT-S International Microwave Symposium (IMS)","volume":"30 1","pages":"607-610"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85926278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This combination allows the realization of a simultaneous compact wireless power and information transfer (WPIT). Each set of the DGS resonators and the Figure-8 inductors are located on the same plane. However, they show negligible coupling due to the coupling cancellation mechanism of the Figure-8 inductors. Hence, high isolation can be achieved between the power and information channels. A prototype is fabricated for operation at 50 MHz and 100 MHz. The overall area of the TX/RX is 30 mm × 30 mm and are separated by 14 mm.

Due to the AE effect, the direction-and the intensity-dependent momentum exchange between the drifting electrons in the Si layer and the acoustic phonons can be utilized to break the intrinsic reciprocity of the ADLs in order to control their frequency response. A 5.2 dB improvement in the IL and a 14.2 dB increase in the reverse isolation (i.e. a 19.4 dB non-reciprocal transmission ratio) is achieved through injecting a 400 µA current in one of the ADLs presented here.
