Dear all,
Could anybody explain to me the stability issues (if any) of Sallen-Key Active Filter?. There are two loops - i) frequency-independent negative feedback loop and ii) frequency-dependent positive feedback loop (this loop's feedback-factor's transfer function is bandpass type). Will there be any phase-margin problem in this kind of filter?
Regards
Samiran
