Description
Summary:In this paper, an efficient bottom-up extraction approach is proposed to build accurate behavioral model for the switched-capacitor (SC) delta-sigma (DeltaSigma) modulator. In the special extraction mode, we can use several specific patterns to obtain the key circuit parameters of the design in a short time without separating it into several sub-blocks. Actual loading effects and parasites can be considered automatically, which makes our modeling approach become more suitable for existed IPs and flattened post-layout designs. In the experiments, the comparison results between our behavioral model and HSPICE simulation have demonstrated the accuracy and efficiency of the proposed modeling strategy.
