Flicker noise in thick film resistors
Abstract
Current noise variations with the shape of a trimmed thick film resistor has been considered. Theoretical results are given by considering distributed current noise sources; the experimental values agree with the theoretical ones. A very large increase in the noise level has been observed experimentally in resistors trimmed with inadequate trimming laser parameters, suggesting an useful way to predict defective cuts.
