This paper introduces a compact microstrip low-pass filter (LPF) with very sharp rejection. The proposed LPF is designed to be used for electronic warfare in defense industry. It has 62 dB/GHz attenuation rate, 10 GHz of stopband width and 48.6 dB attenuation. Moreover, it also wide passband high cut-off frequency (f_c) 6 GHz. been fabricated using alumina (Al2O3) substrate titanium-gold (Ti-Au...

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...

The digitally controlled current conveyor has been used to realize a novel digitally controlled reconfigurable continuous time voltage mode first order multifunctional filter. The realized filter can provide first order voltage mode low pass, high pass and all pass responses. The pole frequency of the continuous time filter is directly proportional to an n-bit digital control word. The realized...

This paper deals with a design method of the analog all-pass filter designated for equalization of the group delay frequency response of the analog filter. This method is based on usage of evolutionary algorithm, the Differential Evolution algorithm in particular. We are able to design such equalizers to be obtained equal-ripple group delay frequency response in the pass-band of the low-pass fi...

In this paper, an optimal design of linear phase digital high pass finite impulse response (FIR) filter using Particle Swarm Optimization with Constriction Factor and Inertia Weight Approach (PSO-CFIWA) has been presented. In the design process, the filter length, pass band and stop band frequencies, feasible pass band and stop band ripple sizes are specified. FIR filter design is a multi-modal...

ABSTRACT A new current-mode universal active-RC filter is proposed. The proposed circuit is based on a new universal passive filter topology. Two Fully Differential Current Conveyors (FDCCII) are used to construct a universal active-RC filter from this passive filter. The FDCCII based proposed filter has only grounded resistances and capacitors as the passive elements. The circuit simultaneousl...

Abstract: This work contains a brief study of a new structure of a low-pass filter of N th order, operating in low frequencies. The low-pass filter is designed with CMOS technology and biased to work in weak inversion. The dimension of the lay-out of the circuit and very low power consumption enables this new structure be integrated in a single chip. The parameter n, dependent of the fabricatio...

In this paper we describe a generic receiver as a single channel S-band receiver and it is composed of two modules. The first module (down converter) consists of an input band pass filter, LNA, image rejection filter and down-converter with a PLL local oscillator. The second module consists of the IF module derived from the VHF receiver. The IF module consists of a low pass filter, 20MHz band p...
