Abstract
Low-frequency noise in silicon MOSFETs is characterized from room temperature down to 5 K. The input-referred noise spectra for n-channel transistors show no gate bias dependence, and the noise amplitude does not change by any significant order of magnitude at all temperatures. While the gate bias dependence in p-channel device flicker noise is observed at low temperature, some generation-recombination noise becomes dominant at temperatures below 30 K
