Abstract :
Two-channel noise measurements are useful for obtaining all four noise parameters of a transistor for circuit simulation and for locating the noise sources inside. It is also easier to stabilise the transistor during two-channel measurements, as only one set of terminations are needed. New matrix equations are derived for de-embedding the system noise for a two-channel measurement system with unidirectional amplifiers that are typically used for low-frequency measurements. The new method is verified by measuring the noise correlation matrices of two-port resistors and applied to the measurement of low-frequency noise of an on-wafer transistor.
