A distributed capacitance model for monolithic inductors is developed to predict the equivalently parasitical capacitances of the inductor. The ratio of the self-resonant frequency (fSR) of the differential-driven symmetric inductor to the fSR of the single-ended driven inductor is firstly predicted and explained. Compared with a single-ended configuration, experimental data demonstrate that the differential inductor offers a 127% greater maximum quality factor and a broader range of operating frequencies. Two differential inductors with low parasitical capacitance are developed and validated.
