ASITIC: Analysis and Simulation of Spiral Inductors and Transformers for ICs
ASITIC is CAD tool that aids the RF circuit designer to
optimize and model spiral inductors, transformers, capacitors, and
substrate coupling. The conductive substrate plays an integral part
in determining the quality factor and self-resonance frequency of
monolothic passive devices. ASITIC calculations include the
electrically induced losses and coupling as well as the magnetically
induced eddy current losses. Skin effect and proxmity effects, or
eddy currents in the matallization, are also included.
A sample ASITIC current density plot shows current
constriction in the inner turns at 5 GHz.
