Abstract
A cryogenic system, called A/C VISCASY, has been built that allows for characterization of electrical devices from room temperature down to liquid helium. A/C VISCASY does not make use of any mechanical system for creating or maintaining the temperature environment. In this way microphonic effects are eliminated when noise measurements of transistors are performed down to very low frequencies. The system is completely programmable and, thanks to its very small cryogenic liquid consumption, can be used for days without refilling. (C) 2003 Elsevier B.V. All rights reserved.
