Design Kit For Spiral Inductors

A parameterized spiral-inductor design kit is based on full-wave simulation.

The kit lets RFCMOS designers create and simulate custom inductor geometries by directly linking Ansoft's HFSS, Ansoft Designer, and Nexxim with UMC's CMOS process parameters. The spiral inductor kit is built upon UMC's Electromagnetic Design Methodology which lets engineers accurately create any RF structure, and gives designers the flexibility to innovate new geometries simply by editing parameters such as diameter, number of turns, width, and spacing of traces from a dialog box in HFSS. Included in the kit are readyto-solve, fully parameterized HFSS projects for circular, square, hexagonal, and octagonal coils in the regular, stacked, transformer and balanced configurations with all vias and underpasses included.
