RC BJT phase shift oscillator?Is there any provision to design the phase shift of a phase shift oscillator?
Could you give a link to such a circuit where the interstage loading is not accounted for?The stage gain including the feedback attenuation must be greater than one. The feedback must be in phase. The common circuit shown in the literature is wrong because it does not account for interstage loading.

You said in post #3 of this forum thread, "The common circuit shown in the literature is wrong because it does not account for interstage loading."See, I told you so. P.S. I wrote this app note with a helper.
What is wrong with the paper in answer 5can any one show figure of a phase shift oscillator using opamp which has already implemented
It's true that you didn't reference any app note specifically in post #3, but when I asked for an example of a circuit that "...does not account for interstage loading.", you didn't respond. Audioguru did however in post #5, and he linked to your app note.The Electrician; you make an incorrect assumption because I did not reference the app note.
It seemed to me that by saying "See, I told you so.", you were telling me that the app note Audioguru linked was an answer to my question asking for a link to "...a circuit where the interstage loading is not accounted for?" Did I misinterpret "See, I told you so."?See, I told you so. P.S. I wrote this app note with a helper.
I did give a reference; I said in post #8: "I only found one page (http://www.play-hookey.com/oscillato...scillator.html) that starts with the (seemingly uncommon, based on my search results) assumption that the unbuffered stages of the phase shifting network don't experience loading effects."Why did you neglect to give references for your web search?
