Abstract
An algorithm of bipolar junction transistor (BJT) amplifier PM and AM noise calculation, described in (1998), is applied to BJT amplifiers, having common emitter (CE) and common emitter-common base (CE-CB) circuit configurations with quartz crystal resonator (QR) inserted in emitter circuits. Power spectral densities (PSD) of PM and AM noise introduced by these amplifiers when signal frequency is close to QR resonance frequency are calculated. Calculations were made for PM and AM noises caused both by wideband noise sources and by sources of 1/f noise. A comparison of PM and AM noises of CE and CE-CB amplifiers is fulfilled and discussed.
