摘　　要：针对片上集成螺旋电感的建模,研究并设计了相关的优化方法。分析了已有电感结构,提出了一种高性能的优化方案,使螺旋电感的品质因数和差分特性都有了显著的提高,为螺旋电感设计中品质因数和电感值的折中提供更大的选择面。该优化设计尤其适合高性能全差分压控振荡器对高性能螺旋电感的需要;优化设计选取典型的单层螺旋电感作为测试对象,工作频率为2.439GHz,芯片面积最大值限定为250μm×250μm,采用ASITIC提供的默认工艺。Based on the existing inductor structures, a high performance approach to optimizing the quality factor and the differential characteristics of the spiral inductor is proposed. It offers more options for trade-offs between quality factor and inductance in the design of spiral inductors. This optimized design can satisfy the demand of high performance full differential VCO for high performance spiral inductors. In this design, typical monolayer spiral inductors are chosen as test object, the operating frequency is set to 2. 439 GHz, and the maximum chip area is defined as 250μm×250μm. Default technology provided by ASITIC is used.
