| Abstract: | Noise factor is the most important one of the technical indicators for amplifier,especially for the low noise amplifier. It is useful for us to optimize amplifier noise factor and improve the performance of the amplifier through strengthening the understanding of the noise factors. This paper deduces the cascade amplifier noise factor formula and puts forward a novel way of understanding. |
