Low-frequency noise measurements were performed on intrinsiclow pressure chemical vapor deposited polycrystalline silicon resistors.The current noise exhibits a transition from 1/f to 1/f 0.6 behaviorwith the resistors biased in the linear region. The origin of the noise isrelated to carrier density fluctuation between conduction band and gapstates consisting of deep states lying close to midgap with uniform energydistribution and exponential band tails. From analysis of the experimentaldata, the quality of the material is characterized with respect to thedeposition pressure. When the resistors are biased in the non-linearregime, an additional noise is observed which is attributed to thetemperature rise due to Joule-induced heating within the samples.
