Frequency-dependent Internal Inductance Associated with Silicon Substrate of On-chip Interconnects

چکیده
In previous work, a closed form expressions for the series line impedance per unit length of a single and multiple coupled interconnects on lossy silicon substrate were presented. In this paper, the induced current density distribution inside silicon substrate and quasi-static Green's function approach were used to derive the frequency-dependent closedform expression for the internal inductance per unit length accociated with the silicon substrate. With this expression, we can quantitatively determine what percentage of the total inductance per unit length is associated with the internal silicon substrate inductance for a given frequency.

Modeling the Substrate Skin Effects in Mutual RL Characteristics of General Asymmetric Coupled Interconnects
The goal of this work was to model the influence of the substrate skin effects on the distributed mutual impedance per unit length parameters of multiple coupled onchip interconnects. The proposed analytic model is based on the frequency-dependent distribution of the current in the silicon substrate and the closed form integration approach. It is shown that the calculated frequency-dependent di...
