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 کاملMeasurement of 1/f Noise in Carbon Composition and Thick Film Resistors
Thermal noise and 1/f noise are known to exist in carbon composition (CC) and thick film (TF) resistors. A circuit involving a differential instrumentation op-amp was used to measure the noise of a resistor under test. The noise spectra of these resistors were measured using a dynamic signal analyzer that performs an auto-correlation Fourier transform from the time domain to the frequency domai...
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 کاملEFFECT OF ANNEALING ON GAS SENSING PERFORMANCE OF NANOSTRUCTURED ZnO THICK FILM RESISTORS
ZnO nano-particles have been synthesized by simple chemical route using a starting solution consisting of zinc acetate and citric acid as a surfactant agent. The structural properties of the prepared ZnO nano-particles annealed at different temperatures have been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) analyses. The XRD patterns show ZnO-wurtize phase...
متن کاملEffects of High Voltage Pulse Trimming on Structural Properties of Thick-Film Resistors
Nowadays, compact and reliable electronic devices including up-to-date ceramic micro-electro-mechanical systems require thick-film resistors with significantly reduced dimensions and stable and precise resistance values. For that reason, instead of standard laser trimming method, high voltage pulse trimming of thick-film resistors is being introduced. This method allows controlled and reliable ...
