摘要
振荡电路的分析是模拟电子技术中的难点问题.将反馈方程与电路框图相结合,导出自激振荡条件,并将自激振荡作为模型用于RC桥式正弦振荡电路的分析.结果表明,该方法能很好地帮助理解反馈型振荡电路的原理,同时能方便确定振荡电路各参数.
The analysis of Oscillation circuit is a difficult problem in analog electronics.Through combining the feedback equation and its block diagram,the generation condition of self-oscillation is established,then taking self-oscillation as a model for the analysis of RC-bridge sinusoidal oscillator.The results show that this method can help understand the principles of feedback-type oscillator circuit well,and determine the circuit parameters easily.
