ACTIVE BIAS NETWORK-BASED MEASUREMENT SET-UP FOR THE DIRECT CHARACTERIZATION OF LOW-FREQUENCY NOISE CURRENTS IN ELECTRON DEVICES

Corrado Florian, Pier Andrea Traverso

Abstract

A technology-independent set-up for the full and direct characterization of short-circuit low-frequency noise currents in two-port electron devices is presented. It is based on the use of low-noise transimpedance amplifiers and a specially-designed active bias network, adopted at the collector/drain port of the device. The features of the set-up proposed allow for a fast and accurate estimation of LF noise current power spectra, within a wide range of DC current bias levels, without the need for any reconfigurations and by carrying out a single-step procedure to achieve each bias point of interest.
