本文给出了一种大动态范围和高灵敏度的检波-放大器
其动态范围可达80dB。文中分析了它的低噪声、检波和放大特性
同时指出了它的设计原则并推导出有关指标的数学表示式。
This paper presents a detector-amplifier with a wide dynamic range (about 80 dB) and high sensitivity
and discusses its characteristics of low-noise detection and amplification. The En-In noise model is analysed
based on this analysis the low-noise design principles are developed and three low-noise properties of the detector-amplifier are discussed.Expressions for the detecting sensitivity
dynamic range
etc. are derived by use of the modified Bessel function and the expansion of its series. Some examples of its practical application are also given.
