Noise Analysis of Transformer-Coupled Preamplifiers

Noise analyses of input stages of typical transformer-coupled preamplifiers are presented. Conditions are derived for which the transformer improves the signal-to-noise ratio of the circuits. Examples are presented which are typical for microphone preamplifiers.
