I want to design active filter with minimal gain of 2 dB with center frequency of 420Khz and pass-bandwidth of 12Khz.
the order should be as minimum as possible to achieve 3db cutoff at 414k -426K.
I tried designing using filter pro software but Q in this case is very high so i am unable to get required results.
the frequency is in middle of High and low frequencies so i am confused whether to use capacitor or inductor.
which topology will be best for this kind of design Sallen Key or MFB?
