电路反馈分类及组态类型判断

Feedback Classification and Judgment of Configuration Types

反馈控制技术已被广泛地用于电子技术领域,其反馈分类及组态类型的准确判断是电路设计的前提和重点.结合分立元件放大电路和集成运放电路两种放大电路,根据反馈采样点、反馈与输入的比较点位置和方式、结合瞬时极性法,提出一种准确判断放大电路反馈极性和反馈组态类型的方法.分析表明,该分类方法和判断法则具有良好的普适性.

Feedback control has been widely used in electronic technology field. Feedback classification and judgment of configuration type are the presupposition and focus of circuit design. With discrete components amplifier and integrated operational amplifier circuit, this text introduces a method combined sampling point, comparison point with instantaneous polarity method to judge feedback configuration and feedback type fast and accurately.
