A low-frequency amplitude and phase-noise measuring system was set up and both noises were measured. It is noted they were correlated in a bipolar transistor. Both noises were from the same origin: diffusion coefficient fluctuation in the base. A demonstration was carried out on the amplitude noise reduction by using the correlation between both noises |
