Abstract :
It is shown that it is possible to realize either a second-order all-pass or a notch filter by a structure consisting of a grounded operational amplifier and two RC one-ports, Y1=G1+sC1and Y2=[R2+(1/sC2)]-1. It is also shown that these filters may be realized by the same structure with Y1and Y2interchanged. These realizations possess minimum sensitivity with respect to the amplifier gain.
