RE: Feedback, no feedback and selective feedback
Posted by Lew on October 10, 2010 at 15:08:35:
Luca, Can you tell us more? For example, exactly where do you put the feedback loop in one of your circlotron designs? Are there decent equations for calculating the values of R and C, such that a non-EE could do it? What output impedance do you shoot for and how do you shoot for it (vs some other lower or higher value)? I am receptive to trying a touch of NFB to bring the output Z down into the range of 1 ohm or below, and I have no problem about your idea of making it frequency-dependent. Thanks.
