We present a novel technique of structural relaxation analysis based on the direct thermal noise measurements on micro-cantilevers and we compare it with the results obtained from the mechanical loss measurements. The dielectric coatings are deposited by ion beam sputtering. The results presented here give a loss angle of annealed tantala and as-deposited silica coatings of (3.9 ± 0.4)·10-4 and (5.8 ± 1.0)·10-4 respectively, from 10 Hz to 20 kHz.","PeriodicalId":447195,"journal":{"name":"2013 22nd International Conference on Noise and Fluctuations (ICNF)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125144945","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}

Three kinds of stresses, short-term isothermal ageing (40°C, hold for 4 hours), long-term isothermal ageing with bias (bias voltage of ±15V, 40°C, hold for 600 hours) and thermal cycling (-40°C to +40°C, 1°C/min, hold for one hour, 20 cyclings), induced degradations in IR have been investigated. The results show that the ageing characteristics of electrical resistance of the samples with the same chemical composition and technological parameters may have the similar behaviour; however, the degradation of LFN shows different trends, and all malfunctions present abrupt increment of LFN. The changes of the noise figure of the samples under three stresses assume that there are two sources of LFN, namely, the contact noise at the solder joints which used to bound the inner Pt leads, and the thermistor bulk noise. The degradations of LFN during the short-term isothermal ageing and long-term isothermal ageing with dc bias may be ascribed to the defects within the thermistor bulk; these two degradations show positive correlation. The degradations of LFN during the thermal cycling may be ascribed to the defects at the contacts. Thus, analyzing the short-term isothermal ageing and thermal cycling induced degradations of the LFN of IR could be an effective screening method, which can significantly shorten the test time.","PeriodicalId":447195,"journal":{"name":"2013 22nd International Conference on Noise and Fluctuations (ICNF)","volume":"258 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116196550","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}

The peak-to-peak value of the transducer mechanical oscillation is in order of tens of the nanometers (for the resonant frequency and two ring transducer). Transducer vibration parameters depend considerably on excitation voltage and frequency. Beyond the resonant frequency some parasitic resonance frequencies are produced. Precise measurement of vibration with nanometer accuracy in the range of the ultrasonic frequencies can be done with using optical interferometry.

This method, based on Onsager reciprocity relationships through the reverse-magnetic-field-reciprocity theorem of Sample et al., allows extracting magnetic field signals whose spectral intensity is much lower than the PSD of the low-frequency (LF) noise observed in the measurement: this includes the LF noise of the Hall sensor, the LF noise of the preamplifier, or the environmental noise due to electromagnetic interferences (EMI). Contrarily to methods based on the lock-in detection principle, which results in a narrow bandpass filtering, the LF-noise-free magnetic sensor signal remains broadband (DC to kHz). An improvement of 30dB in the S/N ratio can be observed around 1 Hz.","PeriodicalId":447195,"journal":{"name":"2013 22nd International Conference on Noise and Fluctuations (ICNF)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116696611","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}

In order to obtain very low levels of equivalent input voltage and current noise, discrete JFETs input stages can be used, with the disadvantage of introducing a large input capacitance that can reduce the usable bandwidth in the case of large source impedances. In this work we propose to employ a modular design entirely based on monolithic operational amplifiers that allows, by paralleling and/or combining in a proper way a number of identical basic amplifier blocks, to reach different compromises in terms of background noise and input capacitance while enabling, at the same time, differential measurement configurations and/or cross correlation background noise reduction approaches.","PeriodicalId":447195,"journal":{"name":"2013 22nd International Conference on Noise and Fluctuations (ICNF)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129481682","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}

Unlike the case of conventional direct knock-on, the second ion that instigates permeation does not need to enter the channel. Nor does it necessarily take the place of the permeating ion at the SF, and it can even be of a different ionic species. The study is based on the simultaneous, self-consistent, solution of the coupled Poisson and Langevin equations for a simple generic model, taking account of all the charges present. The new permeation mechanism involves electrostatic amplification attributable to the permittivity mismatch between water and protein: the arrival of the instigating ion at the channel entrance reduces the exit barrier for the ion trapped at the SF, facilitating escape.","PeriodicalId":447195,"journal":{"name":"2013 22nd International Conference on Noise and Fluctuations (ICNF)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130516522","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}
