摘要：

To measure the current noise in metal contacts and granular resistors, a noise-measuring system with a switched-capacitor filter was used. The samples were crossbar contacts and graphite thick-film resistors. All noise spectra were of the 1/f type. The noise of crossbar contacts and thick-film resistors increases in proportion to the fifth and third power of the resistance, respectively. A model for the noise of metal contacts and granular resistors is proposed. It is based on the spontaneous fluctuation of temperature of the small conducting spots between metal surfaces and granular boundaries, respectively. The results of the analysis are in qualitative agreement with measurements.
