Hi,
i am designing a Butterworth LPF 8nd order with OPA with a frequency cutoff 20Khz. The most important parameter is the current consumption from the circuit (OPA + external component).
I would to know what kind of synthesis technique is the best for my requirement.
The classical Sallen-Key? Or there is another topology with better performance?
Thanks in advice,
