| Outline of Final Research Achievements |
Equivalent circuit representations of fractional-order circuit elements are considered. A ladder circuit representation similar to the transmission line model seems most appealing for its compactness and distributed and therefore nonlocal look. The response of certain distributed circuits can be reproduce by feedback circuits. We therefore looked at the theory of feedback circuits. Theory of transforming a 2-port by embedding it in a 4-port feedback network is established. Transmission lines show fractional-order response at high frequencies. CMOS transmission lines were reported to exhibit strange behavior at millimeter-wave frequencies. Whether such measurement results were real or some artifact wasn’t known. We demonstrated that by properly designing measurement samples, well-behaved characteristics are obtained.
