In this thesis, a hierarchical optimization methodology based on Pareto-optimal front is proposed for large-scale analog/mixed circuits, e.g. PLLs and sigma-delta modulators. At each design level in hierarchy, design performances and design parameters are clear defined respectively. "Simulation-in-a-loop" based automatic sizing process is feasible for large-scale circuits by using the hierarchical sizing strategy. Pareto-optimal fronts constrain the optimization at the higher level under consideration of the capability of building blocks at the lower level. Therefore, a first-time-successful top-down sizing
process without iteration can be accomplished in a reasonable time cost.
