I am designing a fully differential active bandpass filter (around 35-45KHz) so reasonably low frequency.
The circuit is powered from a single 3v3 supply.
I have shown them connected to a low impedance 1v65 supply.
I don't care what the ultimate common mode output voltage is.
However, I was wondering if it is acceptable to just connect Vocm1 and Vocm2 together and bypass with 100n? That is simplest.
OR...
Would a single resistive divider (2k2 + 2k2, say) to generate the 1v65 mid supply for both be acceptable (or even needed if I can just connect Vocm1 and Vocm2.
Thanks.
