Hello,
I came by this configuration and made calculations based on Sallen-Key Equations. The cutoff filter frequency seems as usual but could someone confirm the Q-factor and Damping Coefficient equations of it? Usually, the gain resistor is conected to ground and not tied between C5 and C4.
This is the normal configuration.
