Earlier methods of design have used iterative approaches such as the well-known Parks-McClellan algorithm or some variant of linear programming. Here we give a direct method of design, using Chebyshev polynomials, which provides a reduction in design time over previous methods by about a factor of ten. The ideal equal-ripple response in both passband and… (More)
In this paper different band stop filter topologies have been proposed using MEMS to achieve compactness in comparison with the same class of filter topologies available in literatures. A shift in resonance characteristics and bandwidth is reported by using MEMS switch at various positions. All simulations are carried out using Ansoft HFSS and CST MWS.
