Analytical Calculation of the Inductance of Planar Zig-zag Spiral Inductors
نویسندگان
چکیده
An 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.

This paper presents the design of a multilevel pyramidically wound symmetric (MPS) inductor structure. Being multilevel, the MPS inductor achieves high inductance to area ratio and hence occupies smaller silicon area. The symmetric inductor is realized by winding the metal trace of the spiral coil down and up in a pyramidal manner exploiting the multilevel VLSI interconnects technology. Closed ...
