等价RC正弦波振荡电路的分析与设计

Analysis and Design of Equivalent RC Sinusoidal Oscillators

本文以经典的文氏桥振荡电路为切入点,通过分析RC串并联选频网络和单T选频网络的频率响应,推导出一组与RC文氏桥振荡电路等价的正弦波振荡电路,通过电路仿真实验加以验证,理论分析与电路实验的结果一致。本文对RC正弦波振荡电路的理论教学和实验教学都有一定的指导意义。

Based on the classical Wien bridge oscillator, a set of sinusoidal oscillators equivalent to the Wien bridge oscillator are deduced by frequency responses of a RC series-parallel frequency-selective circuit and Single T frequency selection circuits. The simulative circuits are tested and the simulation results are in agreement with the theoretical analysis. This article has certain guidance meaning for theoretical teaching and experimental teaching of RC sinusoidal oscillator.
