    Abstract: One feature pertains to a digitally controlled oscillator (DCO) that comprises a variable capacitor and noise reduction circuitry. The variable capacitor has a variable capacitance value that controls an output frequency of the DCO. The variable capacitance value is based on a first bank capacitance value provided by a first capacitor bank, a second bank capacitance value provided by a second capacitor bank, and an auxiliary bank capacitance value provided by an auxiliary capacitor bank. The noise reduction circuitry is adapted to adjust the variable capacitance value by adjusting the auxiliary bank capacitance value while maintaining at least one of the first bank capacitance value and/or the second bank capacitance value substantially unchanged. Prior to adjusting the variable capacitance value, the noise reduction circuitry may determine that a received input DCO control word transitions across a capacitor bank sensitive boundary.

    Abstract: Aspects of a method and system for frequency tuning based on characterization of an oscillator are provided. In this regard, a frequency of an oscillator in an integrated circuit may be controlled based on a first digital control word, a frequency of a tuned circuit may be controlled based on a second digital control word, and the second control word may be determined utilizing a mapping between the first control word and the second control word. The frequency of the oscillator and the tuned circuit may be controlled by adjusting a capacitance of the oscillator and tuned circuit, respectively. The mapping may be based on a relationship between the oscillator and the tuned circuit, such as logical and/or mathematical relationship between the capacitance of the oscillator and the capacitance of the tuned circuit and/or the relationship between the frequency of the oscillator and the frequency of the tuned circuit.
