Abstract :
The technique of noise reduction by means of a matching transformer is treated as a modification of the amplifier input noise sources, without resorting to the concept of noise figure. It is shown that matching is independent of the thermal noise of the source. The technique of noise reduction by paralleling input devices is also mentioned as closely equivalent to transformer matching.
