Method and system for frequency tuning based on characterization of an oscillator

A machine-readable storage having stored thereon, a computer program having at least one code section for signal processing, the at least one code section being executable by a machine for causing the machine to perform steps comprising:

• controlling a frequency of an oscillator in an integrated circuit by adjusting a capacitance of said oscillator based on a first digital control word;
• determining a second digital control word utilizing a mapping between said first digital control word and said second digital control word, wherein said mapping is based on a relationship between said oscillator and a tuned circuit in said integrated circuit;
• and
• controlling a frequency of said tuned circuit by adjusting a capacitance of said tuned circuit based said second digital control word.

A system for signal processing, the system comprising:

• in an integrated circuit comprising an oscillator and a tuned circuit, one or more circuits that operate to, at least:
• control a frequency of said oscillator by adjusting a capacitance of said oscillator based on a first digital control word;
• determine a second digital control word utilizing a mapping between said first digital control word and said second digital control word, wherein said mapping is based on a relationship between said oscillator and said tuned circuit;
• and
• control a frequency of said tuned circuit by adjusting a capacitance of said tuned circuit based on said second digital control word.
