On-chip unequal-width spiral inductance calculation method and device

The invention provides an on-chip unequal-width spiral inductance calculation method and device, and relates to the technical field of radio frequency circuit design. The method comprises the following steps: performing equivalent processing on the on-chip non-equal-width spiral inductor to obtain a regular polygon closed concentric metal conductor with equal turns, and determining related parameters of the regular polygon closed concentric metal conductor according to spiral layout parameters and metal related information of the on-chip non-equal-width spiral inductor; according to the relevant parameters of the regular polygon closed concentric metal conductor and the relevant information of the metal, determining the relevant information of the diameter of each circle of metal after equivalence and the center distance between the circles of metal after equivalence, and according to a preset corresponding relation, determining an inductance calculation relevant coefficient corresponding to the number of edg
