In this paper, a design method of a low-frequency universal current-mode filter employing second generation multiple output current conveyors with current amplification function is proposed. Low-frequency filters for biological signals need large capacitances. To realize a large apparent capacitance on a chip, the current amplification factor of the second generation multiple output current conveyors are smaller than one. SIMetrix simulation result shows that the characteristics of the proposed filter are almost the same with the conventional filter. It should be noted that the area of capacitance in the proposed circuit is only 2% in comparison with the conventional filter.
