More parasitic capacitance lowers this upper limit of useful frequency. The total parasitic capacitance of a spiral inductor is a combination of two sources: the interwinding fringing capacitance between adjacent windings and the crossover's parallel-plate (maybe plus some fringing) capacitance, as ...
