Abstract

The invention discloses a pattern ground shielding structure and an inductor. Wherein, the patterned ground shielding structure is arranged on the inductor, and the inductor includes a polygonal inductance coil, wherein the patterned grounding shielding structure includes a structural unit corresponding to each side of the polygonal inductive coil, and the structural unit includes a plurality of polysilicon strips, a plurality of The polysilicon strips form a tower structure with the center of the polygonal inductance coil as the top of the tower. Through the present invention, the effect of reducing the eddy current effect of the inductor is achieved.

Description

technical field [0001] The invention relates to the field of inductors, in particular to a patterned ground shielding structure and an inductor. Background technique [0002] With the rapid development of radio frequency integrated circuits, the requirements for high performance, low power consumption and integration of integrated circuits are getting higher and higher. In order to ensure the stability and uniformity of the integrated circuit process, the design and optimization of the integrated circuit is particularly important. In the entire integrated circuit, the inductor is a widely used component. [0003] In the inductor manufacturing process, there is usually a shielding structure formed by the active layer (AA), polysilicon (Poly), metal (Metal), etc. under the inductor coil (the shielding structure is such as figure 1 As shown), the traditional shielding structure makes the inductor generate a large eddy current during operation. The larger the eddy current, th...
