| 摘 要： | 心电信号是人类最早研究并应用于医学临床的生物电信号之一,对于心电信号的研究,首先要从人体采集心电信号。由于采集到的心电信号比较微弱,所以在处理心电信号的过程中需要一个放大电路来放大信号的幅值以便做后续的信号处理。文中应用集成运算放大器设计了一个可用于心电等微弱信号的后置放大电路,并运用Protel99SE软件对该电路进行性能仿真,并对仿真的结果进行分析,从分析结果中可知该电路可以达到放大心电信号所需要的电压增益。 |

| Abstract: | The ECG is one of the bioelectrical signals that are researched and used in clinical medicine early.Before we want to study it,the first thing is obtaining the ECG from the body.The ECG is very weak,so an amplifier circuit should be designed to amplify its amplitude for signal processing later.In the article,the ECG amplifier circuit was designed using integrated operational amplifier and it was simulated using the software Protel99SE,then,the results of Simulation were analyzed.The circuit can amplify the ECG as we hope it. |
| Keywords: | Protel99SE integrated operational amplifier the ECG amplifier circuit simulation |
