摘　　要：针对学生在进行模拟放大电路实验、参加学科竞赛及课外科技活动时,搭建模拟放大电路的成功率和效率的问题,设计了一种基于运放的多组态放大电路。该电路是数十种模拟放大及滤波电路的结合。利用该电路构成的通用模拟放大电路实验PCB板,直接焊接元件即可完成实验电路搭建,无须再制版。测试结果表明,给出的电路具有较好的实用性,使学生进行模拟放大电路实验的实验效率及成功率显著提高。Aiming at students in analog circuit experiment, in academic competitions and extracurricular activities of science and technology to build analog amplifying circuit when the success rate and the efficiency is not high, this paper designs a multi configura- tion based on the operational amplifier amplifying circuit, the circuit is the conjunction of dozens of analog amplifier and filter circuit. This paper uses the experiment board PCB based the proposed circuit, direct welding component can finish the experiment circuit con- struction. No need to produce PCB additional. The circuit introduced in this paper has good practicality, so that efficiency and success rate of students in analog amplifying circuit experiment are improved obviously.
