【摘要】 本文首先讨论了积分器的工作原理,进而分析自动幅度控制(AAC)积分器这种特殊负反馈环路的控制特性和环路响应,作为AAC积分器设计和测试的依据。我们研制了一种可适应速率范围1～20Mb/s的高速自动幅度控制积分器。本文阐述了这种积分器的电路设计,给出了较为详细的实验测试结果,并对积分器进行了评价。更多还原

【Abstract】 This paper first introduces the operative principle of an integrator, and then the control behaviour and loop response of this novel negative AAC feedback loop is analysed. These serve as the basis of AACI designing and testing. A high speed AACI with rate ranging from 1 to 20 Mb/s has been developed. The circuit design of this AACI is explained; and detailed test results are given. Finally a rough evaluation of the AACI is presented.更多还原
