Optimum Performance in Audio Transistor Amplifiers Using Resistive or Inductive Sources

This report describes the noise figure of a transistor amplifier in the grounded emitter configuration. The effects of biasing, and emitter resistances are included in the noise figure. When the signal source is an inductance such as the reproduce head of a magnetic recorder, the signal-to-noise ratio (S/N) is better measurement of amplifier performance. It is shown that the S/N ratio can be maximized by a suitable choice of inductance, depending upon the operating conditions of the transistor.
