环形振荡器与锁相环的集成电路设计进阶教程：从基础入门到实操进阶，附眼图测试资料与ADE_XL用户指南,新手入门与进阶实战：环形振荡器与锁相环技术，集成电路芯片设计，仿真分析与调谐曲线优化,环形振荡器 ring vco oscillator锁相环 pll PLL 压控振荡器 振荡器集成电路 芯片设计 模拟ic设计[1]没基础的同学，首先学习cadence管方电路+仿真教学文档工艺gpdk180nm，很适合新手入门怎么使用pss+pnoise还有pstab稳定性仿真怎么仿真出调谐曲线，相位噪声功耗，噪声贡献仿真[2]有了上面基础之后，再实操提升进阶有四种经典不同结构的环形振荡器实际电路，工艺是smic55nm有testbench还有仿真状态，直接load即可仿真出波形振荡器频率范围是3GHz以内相位噪声是-90到-100 dBc Hz[3]另外，最后会送眼图，jitter，jee测试方面的资料会送一份一千多页的ADE_XL的User Guide，2018年，IC6.1.8前仿真，无版图， ,核心关键词：环形振荡器; VCO; 锁相环(PLL); 压 <link
