| Abstract: | A fourth-order active filter is presented, which is composed of operational transconductance amplifiers and capacitors. By changing the structure of its input-circuit, it can be used as a current-mode filter or a voltage-mode filter, and each of the both can simultaneously implement the fourth -order highpass, bandpassand lowpass filter functions. The result of computer simulation is present at last. |

| Keywords: | operational transconductance amplifier fourth-order filter highpass bandpass lowpass |
