| Abstract: | 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. |
