## Active -R filters are designed using intemully compensated operational amplifiers (OA) and resistors only. A one-pole or 6 dB roll ofi model for the PA's is assumed in these designs. This model is adequate for active-RC filters. However, for active-R filters such an assumption leads to serious

A closed-form analytical expression for evaluation of the output noise voltage of active-R filters has been developed. 7'he expression is applicable to any low-pass, band-pass or high-pass two amplifier second order active-R realization. The expression for the noise voltage has been derived in terms
