Abstract

In this paper we will demonstrate the benefits of systematic circuit analysis and optimization applied at different abstraction levels of a typical analog and mixed-signal design to address market requirements and technical challenges of nanometer technology nodes. The paper emphasizes the systematic approach using automated analysis and optimization technology in comparison with the still widely spread manual analog design approach led by designers intuition. We chose a double ring oscillator consisting of a Main PLL and a Dither PLL as example to demonstrate how such systematic methodology can even handle large circuits
