Abstract
In one embodiment the present invention includes a method of generating an oscillating signal at different frequencies. The method comprises configuring a digitally controlled oscillator (DCO). The DCO is configured to generate the oscillating signal at a first frequency, and the DCO is configured to generate the oscillating signal at a second frequency. Additionally, the DCO is configured to transition from the first frequency to the second frequency during a transition time period. During the transition time period, the DCO activates the second frequency and deactivates the first frequency during a plurality of time intervals. The time intervals for activating the second frequency and deactivating the first frequency successively increase from the beginning of the transition time period to the end of the transition time period.
