Three new current-mode filter topologies are proposed. The presented topologies use single operational transresistance amplifier (OTRA). To demonstrate the performance of the proposed filter a new current-mode quadrature oscillator is given as an application example. The proposed topologies are simulated PSPICE program to verify the theoretical analysis using a CMOS realization of OTRA with TMSC 0.35 mu m CMOS technology parameters.
