摘要
对宽带直流放大器进行分析和研究。提出基于差分型双渥尔曼组合电路的解决方案,方案电路简单实用,巧妙地解决了直流放大器中的零点漂移问题,并有效抑制共模信号的影响,确保直流工作状态稳定。同时,在交流状态情况下,能有效地扩展通频带宽。
This article analyses and studies broadband DC amplifier. It proposed the solution based on dif- ferential-type double Wallman circuit combinational circuits, which solution circuit has characteristics of simple and practical, ingenious solution to the zero-point drift problem in DC amplifiers, and effective sup- pression of common-mode signal effect to ensure that the DC stable. At the same time, in case of AC sta- tus that can effectively extend the same frequency bandwidth.
