A low-sensitivity active RC low-pass filter

Ahmed M. Soliman

Abstract

A new active canonic RC low-pass filter is given. The sensitivities, with respect to all passive and active circuit components, are low. The frequency limitations of the filter are derived based on the one-pole rolloff model of the operational amplifier (OA) and the results arrived at are compared with other well-known low-pass filters. Experimental results agree with the theoretical ones.
