On the additivity of generation-recombination spectra Part 3: The McWhorter model for 1/f noise in MOSFETs

This is a critical study on the McWhorter model, taking into account the conditions for additivity of GR spectra. A major finding is that the model does indeed give 1/f spectra. The calculated α-values agree with experimental values of MOSFETs in strong inversion. A simple comparison of experimental α-values with values calculated from a Δμ-model or a McWhorter Δn-model does not allow us to decide which the correct noise source is. However, the dependence of α on the gate voltage has often been used as a criterion for the correct source. Nevertheless, the VGT-dependence does not lead to unambiguous conclusions either
