Originální abstrakt

The noise spectroscopy measurement and third harmonic testing was used to investigate effect of the contact electrode geometry and material composition on the thick film resistor quality. It was proved experimentally that noise spectral density is proportional to electric field intensity, while third harmonic voltage depends on the third power of electric field intensity or current density. Modelling of the current distribution for two different shapes of metallic contact cross sections was performed. The electrode geometry plays dominant role for current distribution. The lower value of metallic contact angle, the higher current density peak appears in the vicinity of the contact edge. Effect of cracks, which are found near the contact electrode, also play important role in current distribution, noise sources and non-linearity.
