摘要： A frequency-phase adjusting device includes a first controller, a second controller, and an oscillating circuit. The first controller generates a first control signal according to a target frequency and a current frequency. The second controller generates a second control signal according to the first control signal, wherein the second control signal is related to a first frequency difference, a second frequency difference, and a designated duration. The oscillating circuit adjusts the current frequency according to the first frequency difference, the second frequency difference, and the designated duration. The current frequency is set as a first frequency during a first duration, set as a second frequency during the designated duration, and set as a third frequency during a second duration. The first frequency difference equals a difference between the first frequency and the second frequency, and the second frequency difference equals a difference between the second frequency and the third frequency.
