Ladder-network-based model for interconnects and transmission lines time delay and cutoff frequency determination
Half-T RC ladder networks (LNs) are proven to be first-order models of transmission lines (TLs) and interconnections. In this paper, the determination of LNs electrical characteristics, in terms of internal electrical parameters and number of cells, has allowed to calculate, in an approximated but very accurate way, the time delay and cutoff frequency of open-ended RC LN. Numerical examples on real designs confirm the validity of the proposed method in terms of robustness and accuracy.
