Method for determining inductance of outermost half circle of non-equal-width spiral inductor on non-integer circle chip

The embodiment of the invention provides a method for determining the outermost half-circle inductance of an unequal-width spiral inductor on a non-integer circle piece. The method comprises the steps that half of the equivalently-determined total self-inductance value of regular polygon whole-circle closed metal is determined as the self-inductance value of the outermost half-circle metal of the unequal-width spiral inductor on the non-integer circle piece; determining half of the total mutual inductance value between the outermost whole circle of closed metal and other internal whole circles of closed metal which are equivalently determined as the mutual inductance value of the outermost half circle of metal and the internal spiral metal of the non-integer circle on-chip non-equal-width spiral inductor; according to the self-inductance value of the outermost half-circle metal of the non-equal-width spiral inductor on the non-integer circle piece and the sum of the mutual inductance values of the outermost h
