Abstract

Modern RFICs have achieved an impressively high integration level, making cross-coupling effects among different sections of the circuit a potential limit to their func-tionality. Integrated spiral inductors are a potential source of EM interference. This paper presents a physical equivalent circuit for the accurate wideband modeling of coupling be-tween spiral inductors in CMOS technology, validated by experiments performed on custom test structures. The model proves to be very accurate up to frequencies well above the inductor self-resonance. A simple approximate expression for the mutual inductance is also introduced, useful for the quick estimate of cross talk between different circuit blocks.
