Title: System and method of increasing a self-resonant frequency of a tuning circuit and an oscillator employing the same

Abstract: A segmented inductor for use with a tuning circuit, a method of increasing a self-resonant frequency of a tuning circuit and an oscillator employing the circuit and method. In one embodiment, the tuning circuit includes a first inductive element having a first intrinsic shunt capacitance. The tuning circuit also includes a second inductive element, coupled in series with the first inductive element, having a second intrinsic shunt capacitance. The first and second inductive elements cooperate to reduce a total shunt capacitance associated therewith thereby increasing a self-resonant frequency of the tuning circuit.
