What are the characteristics of on-chip inductors?

Characteristics of On-Chip Inductor The shapes of spiral inductors can be square, octagonal, or circular. These different shaped monolithic inductors can be implemented with a single metal layer or multi metal layers, as shown in Fig. 1 respectively.

How accurate is a CMOS model to predict on-chip inductors?

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-mm and 0.35-mm CMOS processes to demonstrate the prediction accuracy.

Can a distributed capacitance model predict on-chip spiral inductors?

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.

Does on-chip inductance affect power grid noise?

The proposed approach was used on industrial circuits to study the effect of on-chip inductance on delay, crosstalk, and power grid noise. When comparing the PEEC model with the sim-plified loop inductance model, we found that the latter dramati-cally overestimates the impact of signal inductance.

Can a Var-IOUs model be used to analyze on-chip inductance?

The model uses partial inductances, computed using an analytical for-mula for a pair of parallel rectangular conductors spaced in any relative position. We present experimental results, obtained from simulations of industrial circuits, that show the importance of var-ious model components while analyzing on-chip inductance.

What is stacked inductor?

With more and more metal layers available, the stacked inductor, which consists of the series connected spiral inductors, is developed to reduce the area occupied by the planar inductors. Most of on-chip inductor simulators are electromagnetic field (EM) simulators to predict its behaviors such as S parameter and Q.
