ResumoAn analytical procedure for the calculation of the inductance of planar zig-zag spiral inductors is proposed.The procedure is based on the partial inductance concept and models the inductor as a series of a number of parts.The self-inductance of each individual part, which has the shape of a parallelogram, and the mutual inductance between any two parts of the inductor are determined.The inductance of a planar zig-zag spiral inductor can thus be obtained for any width, length and angle of the saw-tooth configuration.The procedure is validated with experimental measurements; the agreement between estimated and measured inductances is very good.
