Disclosed are circuits and methods for increasing an output frequency of an inductance-capacitance (LC) oscillator. In some embodiments, the LC oscillator can be implemented as a voltage-controlled oscillator (VCO) having differential outputs. When the VCO is implemented on a die, wirebond connections from the outputs to a ground results in an effective inductance that impacts a maximum frequency associated with the VCO. An electrical connection such as a wirebond between the differential outputs yields a reduction in the effective inductance thereby increasing the maximum frequency. In some embodiments, the wirebond between the differential outputs can be configured so that its contribution to mutual inductance is reduced or substantially nil.

A method and apparatus is disclosed for voltage-controlled oscillator selection in a multi-mode system having multiple voltage-controlled oscillators. Part of oscillator selection is a calibration operation that utilizes maximum and minimum capacitance limits for a voltage-controlled oscillator, which translates to a frequency range, to calculate overlap regions. Overlap regions comprise frequency ranges that overlap such that the overlap region may be generated by two voltage-controlled oscillators with adjacent frequency ranges. One voltage-controlled oscillator selection routine comprises a real time voltage-controlled oscillator calibration and selection routine that executes every time the system requests a new frequency. Another selection routine comprises a start-up routine that executes only at power up or periodically. Another selection routine comprises a successive voltage-controlled oscillator routine that executes every time a frequency is requested by comparing a requested frequency to different frequency thresholds without executing a calibration operation.
