Abstract :
We measured the phase and amplitude noises and their correlation coefficient in the collector current. The noise-generating mechanism due to the diffusion coefficient fluctuation in the base is discussed, using the distributed constant circuit model. A possible noise reduction method is proposed, using the correlation between the phase and amplitude noises
