Abstract
We have measured low frequency noise in Ge JFETs, Si JFETs and Si MOSFETs. By analyzing the data taken at different temperatures
we have been able to determine the energy level and cross sections of traps that give origin to the Lorentzian noise components.
To do that we have designed a HW/SW system capable to perform measurements between 4K-300K and to calculate the trap's parameters.
Shallow levels have been identified in Ge JFETs. Lorentzian components have been identified in MOS noise spectra.
