Low Noise Electronic Design of Testing Instruments

本文中作者采用了噪声源的输入端等值计算法及噪声器件的E_n-I_n模型推导了有关前置放大器的各级低噪声电路设计公式及低噪声电子设计原则.分析了各种常用前置电路(包括反馈网络)的噪声性能。

This paper introduces low noise circuit design formulae for different stages of correlating preamplifier and principle of low noise eleotronic design derived from the input equivalent algorithm of noise source and E_n-I_n model of noise parts. It also analyses the noise properties of various precircuits (include feedback network).
