Phase-Shift Oscillator
相位移振荡器
|
The phase shift oscillator produces positive feedback by using an inverting amplifier and adding another 180° of phase shift with the three high-pass filter circuits. It produces this 180° phase shift for only one frequency: 相位移振荡器通过使用反相放大器并在三个高通滤波器电路中添加另外180°的相位移来产生正反馈。它仅对一个频率产生这180°的相位移：
 at which the feedback fraction is 反馈分数在哪
B=1/29. |

Calculation notes: If component values are changed, the new frequency will be calculated. If a frequency is entered, then you must click on the active component name of the component you wish to calculate to force the frequency to match the entered value.
计算说明：如果组件值发生变化，将重新计算新的频率。如果已输入频率，则必须点击您希望计算的组件的活动组件名称以强制频率与输入的值匹配。
The frequency expression and the 1/29 feedback factor are derived in Appendix B of Floyd, Electronic Devices. Long, messy expressions!
频率表达式和1/29的反馈因子是在Floyd的《电子器件》一书的附录B中推导的。长长的、复杂的表达式！
