We propose a new DDQ testing signature, the graphical DDQ signature. We discovered that noise, in the entire set of current measurements for a chip, is a vastly superior feature for classifying chips as good or bad, compared to present methods. The measured DDQ current as a function of vectors is defined here as the signature. We examine the shape of the waveform defined by the total set of the...

Oxidation of 3,4-ethylenedithio-3'-iodo-tetrathiafulvalene (EDT-TTF-I) and 3,4-ethylenedithio-3',4'-diiodo-tetrathiafulvalene (EDT-TTF-I2) with DDQ afforded two different salts formulated as (EDT-TTF-I)(DDQ) and (EDT-TTF-I2)2(DDQ)·(CH3CN), both characterized with a full charge transfer to the DDQ acceptor moiety and by short and linear halogen bonding interactions between the iodine atom as hal...

An algorithmic paradigm for I DDQ measurement based analysis that target all two node bridging faults (BFs) in CMOS circuits is presented. In contrast to the pessimistic criteria used in our prior work, here we use the criteria for identifying I DDQ tests proposed in the literature by other researchers. Algorithms for simulation, diagnosis and I DDQ subset selection of BFs in combinational circ...

The one-electron oxidizing capacity of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) improves significantly by visible-light excitation. exited-state DDQ (DDQ*) even converts benzene, fluoroarenes, heteroarenes, benzyls, and olefins into their corresponding radical cations as well chloride other anions radicals. These reactive intermediates have been utilized for the generation C?C C?X (N, O,...

The use of I DDQ test as a defect reliability screen has been widely used to improve device quality. However, the increase in subthreshold leakage currents in deep sub-micron technologies has made it difficult to set an absolute pass/fail threshold. Recent work has focused on strategies that calibrate for process and/or technology-related variation effects. In this paper, a new I DDQ technique ...

OBJECTIVE Drug Craving could be defined as a subjective motivational state associated with a strong desire to consume drugs. Craving is a subjective phenomenon; therefore, self-report (subjective) craving measures are usually referenced. Two well-known questionnaires for measurement of drug craving severity are Desire for Drug Questionnaire or DDQ (for instant craving) and Obsessive Compulsive ...

I DDQ test has been used extensively both as defect reliability screen and as a defect diagnostic technique. However, the increase in subthreshold leakage currents in deep sub-micron technologies has reduced the effectiveness of I DDQ in these applications. Quiescent Signal Analysis (QSA) is a novel diagnostic technique that uses I DDQ measurements made at multiple supply pads on the Chip-Under...

In earlier Fault Analysis (FA) has been exploited for several aspects of analog testing. These include, test development, DfT schemes qualification and fault grading. In present, I testing has become a widely DDQ accepted defect detection technique in CMOS ICs.In this paper we described I testing technique for DDQ analyzing physical faults. A two stage CMOS opamp is taken as Circuit Under Test ...

AIM In the present study the value of the Dental Discomfort Questionnaire in predicting toothache in young children is analysed. METHODS The Dental Discomfort Questionnaire (DDQ-8; Cronbach's alpha 0.75) was completed by parents on behalf of their children (N=99; mean age 47 months). Half of the children were referred to a special dental care centre and the other half were controls from a day...

BACKGROUND The Dental Discomfort Questionnaire (DDQ) is an observational instrument intended to measure dental discomfort and/or pain in children under 5 years of age. This study aimed to validate a previously cross-culturally adapted version of DDQ in a Brazilian children sample. METHODS Participants included 263 children (58.6% boys, mean age 43.5 months) that underwent a dental examination...
