integrators or followers

[Tony Allgood]

Hi there,

Looking at designs using OTA integrators, like SVFs and VCOs. I notice
that some have the cap bolted to the OTA output and ground, and the
signal is then buffered by a follower of some sort. While some have the
cap around an op-amp integrator. Any advantage in doing it this way?
