Noise properties of thick-film resistors in extended temperature range
Results of thorough experimental studies on electrical properties of thick-film resistors (TFRs) have been overviewed and summarized. Experiments covered resistance and noise measurements in wide temperature range. Low-frequency noise spectroscopy has been used for the investigations of fluctuating phenomena. Sample resistors were prepared of various combinations of commercial and laboratory-ma...
متن کاملTransport nonuniversality and critical behavior of the piezoresistive response in thick-film resistors
Thick-film resistors (TFRs) consist of a percolating network of conducting oxide nanoparticles dispersed in an insulating glassy matrix, whose resistive properties are dominated by quantum tunneling across insulating layers separating adjacent conducting grains. Tunneling processes are at the origin of the high sensitivity of the TFRs resistances to applied strains. We have measured transport a...
متن کاملAdvanced electrical and stability characterization of untrimmed and variously trimmed thick-film and LTCC resistors
As-fired thick-film resistors have the resistance tolerance within ±20% and this tolerance is increased for smaller components. Therefore the novel trimming methods are necessary for microresistors, especially when they are embedded in LTCC substrate. This paper compares electrical (normalized temperature dependence of resistance, low frequency noise) and stability properties (relative resistan...
متن کاملThick Film Resistors Ndt by Electro-ultrasonic Spectroscopy
The non-linear electro-ultrasonic spectroscopy was used as a non-destructive testing method for the polymer based and cermet thick film resistors evaluation. We carried out the correlation between this method and standard testing methods as noise spectroscopy and the third harmonic voltage measurements. The measuring set-up with the ultrasonic transducer working on the frequency range 10 kHz to...
متن کاملOn the Origin of Transport Non-Universality and Piezoresistivity in Segregated Conductor-Insulator Composites and Application to Thick-Film Resistors
In this thesis we address the description of electrical transport properties of disordered conductor-insulator composites, mostly by numerical Monte Carlo simulations and analytical study of realistic tunnelling-percolation models. Such composites are basically constituted by conducting particles dispersed in an insulating matrix and present a conductor-insulator phase transition, with critical...
