Design of active linear phase Bandpass filter using Tow-Thomas circuit

In this paper, an active linear phase Bandpass filter design method using Tow-Thomas circuit is given. First, Based on the given specifications, the so called approximation or a linear phase numerical transfer function is calculated. Second, Tow-Thomas circuit building blocks are connected properly according to the obtained transfer function. The symbolic transfer function is then evaluated. Comparing the coefficients of. the two transfer functions, the element values can be determined. A design example is given. The simulated result shows that the design method given in the paper is suitable for engineering applications.I.
