10 Threads found on edaboard.com: Design An Active Bandpass Filter
This isn't actually an active bandpass, rather a passive LC filter followed by a gain stage, which simplifies calculations.
Obviously you got the resonance frequency wrong, but that's no the only design problem. You should face the fact that it's almost impossible to achieve the intended Q of 400 for 6.8 MHz (...)

I want to design an active band pass filter for frequency of 1200Hz to 7000Hz. My center frequency is 2898.2Hz. Can anyone please forward me the circuit based on Opam and the components details?
Thanks in Advance,

Would you please explain more about active BPF design.
I want to design a 160MHz filter with 10MHz bandwidth.

You can use OpAmp to design a filter, use ADS to simulate it.
Why use ADS to simulate an active filter in the kHz range?
There is a lot of free synthesis software for active filters, for example filterPro from Texas Instruments or filterlab from

I have to simulate the noise performances (with Spectre) of an active bandpass filter working up to 1.5 GHz. It's 50ohm input/output matched and what I do not understand is which noise analysis I must use. First, I used Noise analysis in Cadence and during the design I noticed clear noise improvement by choosing the right (...)

At those frequencies, a Chebycheff or Cauer type bandpass filter within an amplifer will be very proper.You can change the capacitor values by switching CMOS transistors that are digitally controlled.For more information, see active filter design methodologies.For inductances, you can use bonding wires and (...)

It's very uncommon to use an active band pass filter with a Q as low as 0.5 because you can realize it with a passive network.
However, it should be possible with the MFB topology.
If you have problems in finding the part values, use a filter design program (available via internet).

i wanna design a bandpassfilter on a FR4 pcb 1.6mm
thickness.The range is between 70Hz and 30kHz.Cutoff frequency at 200Hz and 10kHz.
Pls advise me what type of capacitor to be used as listed below:
Is there any strict rules to make a good design during layout a PCB?
