I first noticed this when my bode plot was greater than 1dB. Now, my bode plot looks correct. undo

Looks like this was due to incorrect definitions of the relationships between R1, R2 and C1, C2 that resulted in the cancellation of the sqrt(mn) term in the omega_0 denominator. This wrong result would imply the corner frequency is independent of the ratio between R1, R2 and C1, C2, which is clearly incorrect. undo Tags: Reverted 2017 wikitext editor
