Analysis of on-chip spiral inductors using the distributed capacitance model
Proceedings. IEEE Asia-Pacific Conference on ASIC, - Trang 259-262
Tóm tắt
The characteristics of on-chip inductors such as the S parameter, the quality factor (Q), and the self-resonant frequency (f/sub SR/) can be determined by its series inductance, equivalent capacitance, and series resistance. In this paper, the distributed capacitance models have been developed to predict the equivalent capacitances of the on-chip spiral inductors such as planar and stacked inductor. Based on the equivalent capacitances formulas, a simple accurate methodology is proposed to build a compact model to predict the behaviors of on-chip inductors. A large amount of inductors have been implemented in 0.25-/spl mu/m and 0.35-/spl mu/m CMOS processes to demonstrate the prediction accuracy.
