Hooge parameters for various FET structures

Abstract
We present here values for the Hooge parameters αHof various FET structures that are one or more orders of magnitude smaller than the value 2 × 10-3that was first proposed. It cannot be said for certain which of these values are due to mobility-fluctuation noise and which represent number-fluctuation noise, but it seems reasonable to assume that the lowest values of αHare more likely due to mobility fluctuations.
