Local oscillator and phase adjusting method for the same |
摘要 |
According to one embodiment, a local oscillator includes: an adder that adds an oscillator integer phase and an oscillator fraction phase and outputs the addition value as first phase information; a delayer that outputs an addition output of a frequency command word at one clock before and second phase information as estimated oscillator phase data; a correcting unit that outputs an addition of compensation information to the first phase information as the second phase information when |the first phase information−the estimated oscillator phase data|>|the first phase information+the compensation information−the estimated oscillator phase data| is satisfied and otherwise outputs the first phase information as the second phase information. |
