摘　　要：分析了已有电感结构,提出了一种独特的高性能的优化方案,使得螺旋电感的品质因数和差分特性都有了显著的提高。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。选取典型的单层正方形螺旋电感作为测试对象,工作频率2．439 GHz,芯片面积最大值限定为250μm×250μm,最小线间距为5μm。Based on the analyzing of the present inductor structures, a particular high performance optimization plan was proposed, which made the quality factor and the difference characteristic of the spiral inductor be remarkable enhanced. This optimized design especially suits the need of high performance entire difference VCO to the high performance spiral inductor. The representative monolayer square spiral inductor was selected as the test object, operating frequency was 2.439 GHz, chip area maximum value definition was 250 μm ×250 μm, and the minimum wire space was 5 μm.
