The PD structure is comprised of two thin film piezoelectric on silicon (TPoS) resonator plates coupled by a silicon beam in the middle. The device exhibits a width extensional resonance mode in which resonant plates vibrate out of phase. When actuated in this mode, the interference of acoustic waves generated from both plates determines the consequent displacement amplitude, and therefore the output signal. Such structure operates as an analog exclusive-OR gate, in which input signals with an identical phase lead to a destructive interference of acoustic waves and therefore a minimum output signal. Out-of-phase input signals (constructive interference), on the other hand, results in the maximum output voltage. Phase sensitivity as high as 1.3 mV/Deg was observed with minimum detectable phase error of 0.006° associated with 8μVrms output voltage standard deviation. Such PD can potentially be used in a MEMS-based analog phase locked loop (PLL). Noise reduction due to the pass-band filtering inherent in the operation of this PD, along with its minimal power consumption are the benefits of the resonant PD over its electronic counterparts.","PeriodicalId":122928,"journal":{"name":"2016 IEEE International Frequency Control Symposium (IFCS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127530413","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}

As a consequence of the light-shift effect, variations in the lamplight's intensity result in variations in the RAFS' output frequency. While the basic physics of the light-shift is reasonably well understood, its operational implications for GNSS performance are only beginning to be fully appreciated. Here, we summarize results examining decade-long histories of on-orbit GPS RAFS lamplight variations. In addition to a deterministic variation that is well modeled by the sum of an exponential and linear trend, the stochastic variations appear to be of three types: lamplight jumps, repeating lamplight ramps, and non-stationary lamplight noise. Employing an estimated GPS RAFS light-shift coefficient, these variations can be used to infer lamplight-induced RAFS frequency variations.","PeriodicalId":122928,"journal":{"name":"2016 IEEE International Frequency Control Symposium (IFCS)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126612746","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}

Compared with the storage of hydrogen by high-pressure gas technology, the storage by solid alloy in the same volume decreases the pressure by almost one order of magnitude. The reliability of hydrogen source is improved by the technology of metal detection, bulge test and mass spectrometer leak detection. According to the tests of hydrogen source bleed platform and assessment of long lifetime, a mathematical model of hydrogen source is built up, predicting the lifetime of hydrogen source to more than 12 years.
