Synthesis of Active Distributed RC Networks

This work presents a general method for the synthesis of any open-circuit transfer function, which is expressed as a rational function with real coefficients. It is shown that such functions can be realized by using two distributed RC elements (modified by active units if necessary), one negative impedance converter and one lumped capacitor. The distributed RC element used here is a three-layer structure, a pure dielectric sandwiched in between a perfect conductor and a resistive film.
