本文扼要介绍一种新型快、慢环结构的直流耦合宽带放大器。运用节点分析法对有快、慢环结构的FH4-056型相加器进行分析,导出稳定条件及带宽表达式。估算了直流漂移值并同实验结果作了比较。
This article briefly introduces a new fast and slow-loop DC-coupled broadband amplifier. The node analysis method is used to analyze the FH4-056 adder with fast and slow loop structure, and the stable condition and the bandwidth expression are derived. The DC drift is estimated and compared with the experimental results.
