Abstract

See full text

A digitally controlled oscillator that generates an output frequency according to input data includes a determination unit that determines whether the input data has a value that causes deterioration in a phase noise characteristic of the digitally controlled oscillator, an offset unit that offsets the input data when the input data is determined to have the value that causes deterioration in the phase noise characteristic, and a generating unit that generates the output frequency using the input data after being offset.
