A case study based on the 6-transistor transconductor circuit is discussed. The five-fault model is assumed per transistor, namely a short circuit between any two terminals as well as an open-circuited drain or source. DC testing is performed in order to reduce test cost instead of AC testing which requires expensive equipments. Only one fault is assumed to exist in the circuit under test. PSpice simulations have been carried out using the 0.18µm MOS model provided from MOSIS. The circuit has been simulated for fault-free condition and after injecting a single fault at a time into the circuit. The simulation results have been analyzed and compared. It is found that the total fault coverage is 93%.","PeriodicalId":228594,"journal":{"name":"2010 12th Biennial Baltic Electronics Conference","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133563484","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 photoplethysmographic signal was analyzed by calculating the differences between pulse waveforms. In addition waveform amplitude and the slope of the rising front were studied. When the applied pressure was lowered to the level where the piezoelectric signal amplitude is near its maximum, the differences between pulse waveforms decrease. It was concluded that there is a critical pressure level and below this the waveform is no longer influenced.","PeriodicalId":228594,"journal":{"name":"2010 12th Biennial Baltic Electronics Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115941941","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}

Double-beam spectrophotometer (Shimatsu UV-2401 PC, Japan) was used for the determination of UV-absorbance in the collected spent dialysate samples. Due to differences in independent variables included two multiwavelength models were developed using stepwise regression. The coefficient of determination, R2 was 0.8709 for the first and 0.8756 for the second model. The standard errors were 15.86 micromol/l and 16.01 micromol/l, respectively.

The same frequency was detected with all the EMFi strip sensors differing mainly in the amplitude of the detected frequency. The amplitude of the snoring frequency was proportional to the recording location on the skin of a person.

It has been shown that the linearity of the interface output with respect to input acceleration is infinity at DC input signals when half-bridge sensor element is assumed as parallel plate capacitor pair. The linearity degrades as the input signal frequency gets higher. The source of the non-linearity is found out to be the phase difference between senor sensor element displacement and the interface output voltage. The analytical expression for the HD3 of the interface is derived. It has been seen that to increase the linearity of the interface, the phase difference can be decreased by increasing the cut-off frequency of the interface loop.","PeriodicalId":228594,"journal":{"name":"2010 12th Biennial Baltic Electronics Conference","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126707749","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}
