Abstract :
We present a characteristic function approach to parameter extraction for Si-based on-chip spiral inductors with a center tap. A closed-form analytical expression to extracting the model parameters specifically for the center tap branch is developed. The model parameters can then be extracted analytically. The validity of the present approach is verified by measurement based on 0.18 ¿m CMOS process.
