LF747集成双运放计算机模拟及版图设计

Computer simulation and layout design of integrated double operational amplifier LF747

以逆向设计为主导方向，对国外集成双运放ＮＳＣ７４７原理电路进行了模拟分析，并与国内同类产品做了对比实验，设计出了改进型的ＬＦ７４７电路版图。

Taking the retrorse design method as a leading way, this paper makes simulation analysis for the principle circuit of the foreign integrated double operational amplifier NSC747. The experiments compared to the domestic same products are made, and the improved circuit layout LF747 is designed.
