This paper demonstrates the application of craziness based particle swarm optimization (CRPSO) technique for designing the 8th order low pass Infinite Impulse Response (IIR) filter. CRPSO, the much improved version of PSO, is a population based global heuristic search algorithm which finds near optimal solution in terms of a set of filter coefficients. Effectiveness of this algorithm is justifi...

157 Abstract— In this paper, voltage -mode and a current-mode Kerwin-Huelsman-Newcomb (KHN) filter structure employing current feedback amplifiers (CFAs) is proposed. Both circuits perform three standard functions including low-pass, high-pass and band-pass functions. The current mode filter is multi-input and single-output (MISO) type whereas voltage mode filter is single-input and multi-outpu...

In this paper, a channel drop ring resonator filter based on two dimensional photonic crystal is proposed which is suitable for all optical communication systems. The multilayer of silicon rods in the center of resonant ring enables one to adjust resonant wavelength of the ring and enhance power coupling efficiency between ring and waveguide. Refractive index and radius of multilayer rods insid...

A low voltage square root domain filter based on the MOSFET square law is proposed. Through the verification of HSPICE simulation, the extendibility and the reliability of the design procedure are proven. A design technique for current-mode square-root domain band-pass filter simulation in a 0.18 μm CMOS process. The basic building block consists of current-mode current mirrors, square-root cir...

In order to reduce the effect of Inter Symbol Interference (ISI) in a digital communication system, different types of transmitting pulse shaping filters have been extensively used in practice. We need to design these filters with some constraints imposed by requirements of the communication system in which we are going to use them. The use of optimization techniques have been proved to be quit...
