摘 要:正弦波振荡电路是模拟电路课程的基本教学内容,几乎所有的教材都采用反馈的概念来分析正弦振荡
电路的特性。本文通过列写文氏桥式振荡电路的电路方程,分析了该电路的振荡特性,并采用数值仿真的方法
模拟起振条件,得到了与现有教材对该电路分析一致的结果。上述分析结果可供讲授电路理论及模拟电路课
程的教师参考。

Abstract :Sinusoidal oscillating circuits are the fundamental parts in the course
of Analog Circuits. Almost all the text books analyze the oscillating circuits
using the concept of feedback. Fundamental circuit analysis is applied on Wen's
bridge oscillating circuit and circuit equation is deduced to analyze the
circuit's oscillating characteristics and its starting condition for oscillation
which concords with the text books. Numerical results are given through computer
simulation. The analysis results are helpful for the teaching of circuit theory
and analog circuits.
Keywords :Wen’s bridge oscillating circuit ;circuit analysis ;numerical simulation
