Simulation Error Analysis and Correction of Schmitt Oscillation Circuit Based on NE555

文章对基于NE555的中低频施密特振荡电路的Proteus仿真设计中出现的误差进行了分析,提出了误差产生的原因,因为NE555的非轨对轨输出,给出了基于输出电压修正的误差修正方法和实现过程,通过实验验证了修正方法的可行性和准确性。

This article analyzes the errors in Proteus simulation design of medium and low frequency Schmitt oscillation circuits based on NE555,and then proposes that the reason for the errors is the no rail-to-rail output of NE555.Finally,it provides an error correction method based on output voltage correction and implementation process.The feasibility and accuracy of the correction method are verified through practical experiments.
