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.
