“…Since the absolute value of the group delay can be electronically adjusted in the filter using integrators with variable characteristics, the flatness of the group delay is of special interest. It is well known that all sensitivities of the group delay for each element cannot be zero in an active RC circuit [10]. Hence, it is difficult to reduce the effect of the parasitic capacitance by making the element sensitivity small for all C i and G i .…”
