In this paper, a new universal current-mode filtering circuit with single input and multi-outputs based on OTAs (operational transconductance amplifiers) is proposed. The circuit just consists of two operational transconductance amplifiers, one current controlled current amplifier with multi-outputs (MO-CCCA), and two grounded capacitors. It can realize low-pass, band-pass, high-pass, band-stop, and all-pass filters simultaneously. Its quality factor and natural frequency can be tuned independently and the sensitivities are very low. Moreover, the non-ideal characteristic of the proposed filter is analysed and simulated by PSPICE. [ABSTRACT FROM AUTHOR]
