It is well known that several active filters with better high-frequency applications can be designed by using the one-pole roll-off representation of the operational amplifier (OA) However, the dynamic range of such active filters is narrow because the maximum output voltage of an OA without any distortion of the wave form is limited by its own slew rate at high frequencies In this report, a simple methd is presented to improve the maximum allowable for signal magnitude of second-order active RC filtere at the top end of the dynamic range Our major points is to use the resistor dividers which are additionally connected to the differential input terminals of an OA The improvment factor of the dynamic range is limited by the value of GB/Qωo
