直饋包围多级放大級的設計——宽频带运算放大器
THE DESIGN OF AMPLIFIERS WITH FEEDFORWARD AROUND MULTISTAGES —A WIDE-BAND OPERATIONAL AMPLIFIER
-
摘要: 本文提出直馈包围多级放大级线路设计的一种方法。基于对实际合成特性的分析,利用两个矢量不等式,获得了设计该几级放大级频率特性的基本准则。利用所提出的方法分析了一个典型线路并给出符合理论分析的实验结果。Abstract: Based on the analysis of the composite characteristic of amplifiers with feedforwardaround the amplifier, using two vector inequalities the design criterion of their frequencycharacteristic is obtained. These principles are applied to the analysis of a typical am-plifier circuit. Experimental results which check the theoretical analysis are given.
