Design Of Stable Narrow Band-Pass Filter Using Multi-Stage Biquad Topology, Raman Attri
Design Of Stable Narrow Band-Pass Filter Using Multi-Stage Biquad Topology, Raman Attri
Raman K. Attri
Band pass filtering techniques have been a challenging task due to requirement of keeping Quality factor, gain and mid-frequency of the filter independent of each other. Other most important aspect is keeping the filter stable, keeping mid-frequency immune to circuit component tolerances and to achieve the mid-frequency at the accurate value. The Biquad family of topologies are typically used for a stabilized filtering application, however the design requirements on Biquad topology for low frequency application is still a challenge. The requirements become more stringent for bandwidth curve, roll-off curve and preciseness of frequency filtering as we move down to low …

Practical Design Evaluation Of Extremely Narrow Band-Pass Filter Topologies, Raman K. Attri
Raman K. Attri
Narrow Band pass filtering techniques have been a challenging task since the inception of audio and telecommunication applications. The challenge involves keeping Quality factor, gain and mid-frequency of the filter independent of each other. Other most important aspect is keeping the filter stable, keeping mid-frequency immune to circuit component tolerances and to achieve the mid-frequency at the accurate value. The requirements turns more stringent when working with low frequency Narrow band-pass filters where the shift in few Hz would cause great frequency errors. The selection of right topology for best performance is the key top successful design. This paper objectively …
