Abstract

The computer-controlled system for low-frequency noise measurements has been presented. All major functions for adequate polarisation of a device under test are programmable providing complete flexibility and automation for biasing. The inherent noise parameters of the main modules are enclosed. The system enables to measure input-output noise relations for BJTs, JFETs, MOSFETs, MESFETs, HEMTs, and, in general, also other two-ports.
