Despite enormous developments in semiconductor technology low frequency noise is still a problem. It is an important factor determining C/N ratio of modern communication equipment (phase noise in oscillators, noise in direct conversion receivers, etc.). Its value can not be theoretically predicted with the needed accuracy. At the same time low frequency noise reflects internal processes of semiconductor devices. Targeted noise measurement can be used to determine some specific semiconductor technology features [1,2] that could lead to technology improvements. Therefore, experimental determination of noise parameters during the manufacturing process is of utmost importance. These parameters are also used in SPICE and other simulation software models instead of the default simplified 1/f noise model [3,4]. In this paper features of three widely used noise measurement circuit configurations are analysed and application options discussed. Methodology of measurement data processing and extraction of 1/f noise parameters is proposed. As an example analysis of FET noise measurement and parameter extraction is given.
