Abstract

Differential equations are derived for a symmetric transistor trigger and multivibrator. It is shown that the equations can be derived using the author’s expression for the current characteristic of a common-emitter transistor amplifier based on the Lambert W function (in spite of the fact that the equations can be formulated using different characteristics). The equilibrium state for the differential equations of the trigger is studied. Slow and fast motions are analyzed for the differential equations of the multivibrator. A numerical solution for the multivibrator is presented.

触发器和多谐振荡器的微分方程

摘要

为对称晶体管触发器和多谐振荡器推导出微分方程。结果表明，可以使用作者基于 Lambert W 函数的共发射极晶体管放大器的电流特性的表达式推导出这些方程（尽管可以使用不同的特性来公式化这些方程）。研究了触发器微分方程的平衡状态。对多谐振荡器的微分方程进行慢速和快速运动分析。给出了多谐振荡器的数值解。
