| Abstract: | The design and realization of the amplifier of low noise and interference-proof has been one of current important research topics,along with more and more demands from many fields to receive weak signals.This paper studies the design principle of low noise and interference-proof amplifier in detail.Through considering the characteristics of SLF noise,we suggest a realizable scheme of SLF low noise amplifier.The experiment shows that using this method we can realize a SLF low noise amplifier with stable performances and meeting design requirements. |
