    Abstract: Apparatus and associated methods relate to automatically generating a data structure representation of an on-chip inductive-capacitive (LC) tank circuit by determining parasitic inductances in each of the segments of conductive paths that connect a main inductor to one or more selectable VCO components such as capacitors and varactors, for example. In an illustrative example, one or more of the selectable VCO components may be arranged, when selected, to form a parallel resonant LC tank with the main inductor. A method may include defining nodes ai terminating each of the segments along the conductive paths between the main inductor terminals and a drive circuit. By modelling the paths as multi-port inductors and transformers, resonant frequency of the VCO may be more accurately predicted by simulation.
