A new circuit topology realizing a first-order currentmode all-pass filter is proposed using two dual-output second generation current conveyor and two passive components. The circuit possesses low-input and high-output impedance, which makes it ideal for current-mode systems. The proposed circuit is verified through PSPICE simulation results. Keywords—active filter, all-pass filter, current-mo...

A novel type of dual-mode microstrip bandpass filter using degenerate modes of a meander loop resonator has been developed for miniaturization of high selectivity narrowband microwave bandpass filters. A filter of this type having a 2.5% bandwidth at 1.58 GHz was designed and fabricated. The measured filter performance is presented.

This work presents a novel compact dual bandstop filter (DBSF) using planar modified radial stub connected in shunt with 50 Ω microstrip line. The simulation results of the DBSF filter demonstrates good dual wideband bandstop filter (BSF) characteristics with 3 dB stopband fractional bandwidth of 65.42 % and 34.23 % at f1 = 2.4 GHz and f2 = 5.2 GHz resonating frequencies respectively. The inser...
