Abstract

Various high-order transconductance-capacitor active-filter structures are analysed by means of noise flow graphs. Their noise performances are compared for different 4th order lowpass approximation designs. Contrary to the known active-RC property, the inverse-follow-the-leader configuration does not exhibit optimal noise.
