Abstract
An apparatus permitting measurements of current and voltage thermal noise of two terminal devices has been built using a correlator amplifier and a controlled amplitude white noise generator. It allows accurate determinations of device impedance components, especially of nonlinear devices such as thin ferroelectric capacitors.Keywords
