Opis :
To completely characterise the noise behaviour of a two port device, four noise parameters Fmin; Rn; Gopt ; and Bopt must be determined. This paper reports improvements in the uncertainty related to the above parameters, taking into account measurement errors due both to the limited instrument precision and connection repeatability. Results are reported for noise characterisation of 0.3 mmd -doped HEMT devices by Alenia, demonstrating as the common hot-cold measurement procedure can result with an error confidence as low as 0.2% for all the noise parameters.
