In order to solve problems of high power consumption and narrow bandwidth, a new current-mode nth-order multifunction filter circuit was presented. It is composed of one CCII(second-generation current conveyor),one CDCTA(current differencing cascaded transconductance amplifier) and grounded capacitors. The proposed filter enjoys the simple structure and the circuit power consumption is only 6.82 mW, the maximum sensitivities value is only 1 and the circuit bandwidth is over 100 MHz. Moreover, its bandwidth can be tuned electronically. PSpice simulation and hardware experiment have been included to verify the theoretical analysis.
