ABSTRACT:
A PLL receives an indicator indicating that it is to operate at a different operating frequency than a current operating frequency. A control word is selected from a set of linear control words based upon the different operating frequency. A capacitance of a variable capacitor of a voltage-controlled oscillator is adjusted based upon the control word. The variable capacitor is monotonic and non-linear relative to the set of linear control words.
