This paper proposes a multi-input single-output MISO third order voltage mode VM universal filter using only one operational transresistance amplifier OTRA. The proposed circuit realizes low-pass, high-pass, all-pass, band-pass, and notch responses from the same topology. The PSPICE Simulation results using 0.5 μm CMOS technology agree well with the theoretical design.
