Modeling and Analysis of CMOS Differential Inductors and Series-Connected Inductors
CMOS差分电感和串联电感对的建模与分析

This paper models and analyses differential inductors and series-connected inductors from SMIC’s 0.18μm CMOS process, and then proposes a design rule of inductors in RF CMOS differential circuits. This paper also presents a new model of series-connected inductors, in which mutual inductance, substrate capacitive loss and capacitive effects between windings are taken into consideration. Finally, a group of series-connected inductors with different spacing are designed and fabricated, and their measured results verify this model.
