A New On-Chip Substrate-Coupled Inductor Model Implemented With Scalable Express

Abstract

Accurate modeling of the on-chip inductor is essential for the design of high-speed, low-power, and low-noise radio-fre- quency integrated circuits. The conventional model has a measur- able discrepancy as the current flowing in the substrate is not cor- rectly considered. The substrate-coupled inductor model, however, considers the losses generated in both the vertical and horizontal directions. This model gives an intelligent explanation of the re- duction in equivalent resistance between termi
