The electrical performance of silicon-based spiral indicator constituted with multi-layer metal is studied by the combined method of theoretical analysis and electromagnetic simulation. The silicon-based RF high-Q indicator applied to RF cir-cuit integration was optimized and acquired. Among various loss mechanisms influencing Q-value of the indicator,the influence of skin effect on the indicator is researched emphatically. The silicon-based Q-value of the indicator after optimizing the struc-ture parameter and the metal stacking can reach 60,and the self-resonant frequency can achieve 10 GHz. The inductor can be better applied to networks of filtering,frequency-selecting and matching in RF system.
