Implementation of an Inductorless 5th Order Band-Pass Filter
This paper demonstrates the design and implementation of an inductorless analog band-pass filter (BPF). Band-pass filters are widely used in communication systems, wireless transceivers and audio systems, they only pass signals within a desired frequency range. The principles mentioned in this article can be generalized to design any analog filter regardless of its order, approximation and prototype. The design procedure can be broken down into three main parts, first of all, a passive low-pass filter (LPF) is implemented, then the passive LPF is converted into a passive BPF. Finally, the passive BPF is transformed into an active BPF by adding operational amplifiers. The active BPF is then modified into two different topologies, the first in which the inductors are replaced with simulated- inductors (gyrators), while in the second topology, less operational amplifiers are used.
