it was required to design a band pass filter with some specifications so i used the chebyshev approximation till i reached the desired TF and started to implement it using diff stages from the op amps at last i got this response which is good but at the center frequency there is a 7db gain about 2.2 in magnitude that’s gonna make problems in the transient response so i wanted to get rid from these gain without affecting the band width of the filter (i have tried to add inverting op amp stage to get rid of this gain and it’s completely reduced but unfortunately affected the bandwidth )
