This paper presents a universal current-controlled current-mode biquad filter employing current controlled current conveyor trans-conductance amplifiers (CCCCTAs). The proposed filter employs only three MOCCCCTAs and two grounded capacitors. The proposed filter can simultaneously realize low pass (LP), band pass (BP), high pass (HP), band reject (BR) and all pass (AP) responses in current form ...

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...

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...

brain-computer interfaces (bci) record brain signals, analyze and translate them into control commands which are relayed to output devices that carry out desired actions. these systems do not use normal neuromuscular output pathways. actually, the principal goal of bci systems is to provide better life style for physically-challenged people which are suffered from cerebral palsy, amyotrophic la...

Abstract—This paper presents a voltage mode universal biquadratic filter with one input and five output terminals, realizing all the standard filter functions that are high pass, band pass, low pass, notch and all pass, without changing the circuit topology. The proposed circuit employs three plus-type differential difference current conveyors (DDCCs), three grounded resistors and two grounded ...

This paper presents semicircular microstrip low pass filter with the sharp rejection and wide stop band. The proposed filter design is based on the calculations of filter parameters from traditional Hi-Lo impedance method and is available in the literature of microstrip filter. To further improve the design performance, high impedance lines are magnetically coupled, resulting an attenuation pol...
