Matching Analysis of Front-End Amplifier Chain & Digital A/D Module Interface
摘要
Abstract
The problem of matching between a receiving front-end amplifier chain and a digital A/D converter module is explored in details. Then the limit performances of a receiving system sensitivity and dynamic range are analyzed when the front-end amplifier chain and the digital A/D converter module are interconnected. An experimental test results is presented to demonstrate and compare with our deduction values in theory. Several compromising suggestions on choosing the right gain of an amplifier chain and a proper AD converter are given. Some aspects and referential curves on receiving system design are summarized which is used to obtain the required sensitivity and dynamic range within the available performances of the front-end and the digital A/D converter modules.关键词
