Method for synthesizing frequency and electronic device thereof

摘要

An electronic device for synthesizing a frequency is provided. The electronic device includes a bank changer configured to output a channel code corresponding to a reference frequency signal and a feedback frequency signal, a channel code mapper configured to generate a changed channel code by applying an offset to the channel code output from the bank changer, and a voltage controlled oscillator configured to control a total capacitance of a plurality of capacitors based on the changed channel code and to oscillate a frequency dependent on the total capacitance.

1. An electronic device for synthesizing a frequency, the electronic device comprising:
a changing unit configured to output a channel code corresponding to a reference frequency signal and a feedback frequency signal; a mapping unit configured to generate a changed channel code by applying an offset to the channel code output from the changing unit; and a voltage controlled oscillator configured to:
control a total capacitance of a plurality of capacitors based on the changed channel code, andoscillate a frequency dependent on the total capacitance, wherein the offset is determined to exclude an error channel code from channel codes output from the changing unit, and wherein the error channel code causes an interval error between oscillation frequencies.
