Abstract

An investigation of laser‐trimmed thick‐film resistors’ current noise was carried out. A large number of samples from two pastes with different P‐ and L‐cuts were prepared. The noise spectrum of the trimmed resistors was measured to obtain a relationship between the current noise and the cut parameters. A simple but comprehensive electrical model for the simulation of the current noise of trimmed resistors is also presented. The results from the noise simulation agree with the measured data.
