In this paper, a new three input single output trans-admittance mode biquad universal filter is proposed, which employs only single active element, namely modified differential voltage current conveyor trans-conductance amplifier (MDVCCTA) and four passive elements in the form of two capacitors and two resistors. Two of the passive elements used in the proposed structure (one resistor and one c...

A new universal current mode filter circuit composed by three multi-output second generation current conveyor circuits (MOCCII), two controlled active resistances and two passive capacitors is presented. This filter can realize all the five standard filter functions, namely low pass, band pass, high pass, notch and all pass, without changing the circuit topology. TSPICE simulation using 0.18 μm...

Filter design takes one of two approaches: passive or active. Passive designs combine resistors, capacitors and inductors to perform specific frequency filtering in applications where precision is less important than mass producibility. For very high frequency applications, a passive approach is quite often the only way to go. Active filters combine op amps and discrete transistors, primarily w...

This paper presents a new multi-passive-sensor target tracking algorithm which yields a nonlinear state estimator called Gaussian filter based on deterministic sampling. Firstly, this state estimator employs a deterministic sample selection scheme, where a parametric density function representation of the sample points is employed to approximate the cumulative distribution function of the prior...

this paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. the power filter integrates a passive power filter which is a rl low-pass filter placed in series with the load, and an active power filter which comprises an rl in series with an igbt based voltage source converter. the filter is assumed...

Electric arc furnace (EAF) is one of the responsible cause for deteriorating power quality in the distribution network by, introducing harmonics, propagating voltage flicker and causing unbalance in voltages and currents. This paper presents performance evaluation of composite filter (CF) for power quality improvement of EAF distribution network. The performance of CF is evaluated in terms of h...

Recently, multilevel inverters are more researched due to the advantages they offer over conventional voltage source inverters in grid connected applications. Passive filters are connected at the output of these inverters to produce sinusoidal waveforms with reduced harmonics and to satisfy grid interconnection standard requirements. This work proposes a new passive filter topology for a pulse ...
