多电抗LC反馈振荡器状态及类型判定
|
摘要
LC反馈振荡器的状态及类型判定是高频振荡电路应用中的一个技术关键点.对于放大器各支路含有单个电抗元件的LC反馈振荡器,其状态及类型的判定可直接由三点式振荡器判定准则给出,但对于各支路含有多个电抗元件的LC反馈振荡器,其状态及类型的判定则比较复杂.给出了基本的支路单电抗LC反馈振荡器判定准则,然后将其推广到支路多电抗的LC反馈振荡器中,并给出了分析法和特性图法两种判定方法,从而使所给准则能够更好地满足LC振荡器状态及类型判定的应用需要.
The state and type judgment of LC feedback oscillator is one of key technique points in the application of high frequency oscillating circuits.For the LC feedback oscillator with one reactance component in each branch of amplifier,its state and type judgment can be fulfilled by the constitution rule of the LC feedback oscillator;but for the LC oscillator with multiple reactance components in each branch of amplifier,the judgment on its state and type will become relative complicated.To solve this problem,we start from the judgment rule of basic LC oscillator with one reactance component in each branch of the amplifier,and then we generalize it to the case of LC oscillator with multiple reactance components in each branch.Meanwhile,we present two judging methods,namely,analytical method and feature graph method,accompanied by the detailed explanations,and from this we can apply the rule better to the state and type judgment of LC oscillator.
