Frequency-independent equivalent circuit model for on-chip spiral inductors

Abstract

A wide-band, physical and scalable 2-/spl Pi/ equivalent circuit model for on-chip spiral inductors is developed. Using frequency-independent RLC elements, it accurately captures R(f) and L(f) characteristics beyond the self-resonant frequency. This new model is fully compatible with both AC and transient analysis. Verification with measurement data demonstrates excellent scalability for a wide range of inductor configurations.
