The major noise sources in a bipolar transistor are the base resistance thermal noise, or Johnson noise, the base current shot noise and the collector current shot noise. The shot noise is described by a spectral density of 2qI, I being the DC base, I/sub B/, or collector, I/sub C/, current. We present a detailed microscopic treatment of the transistor collector current shot noise, which is typically given as a macroscopic result of electrons passing through the EB junction barrier.
