Abstract: PURPOSE: A broadband frequency synthesizer and a method thereof are provided to improve the reliability by executing an elaborate lock up operation. CONSTITUTION: A frequency selector(520) selects a broadband frequency by receiving a frequency divided signal which is divided according to a reference signal and a floating point frequency division ratio. A cap bank voltage controlled oscillator(513) is controlled with the frequency selector. The cap bank voltage controlled oscillator outputs a broadband frequency. The frequency selector comprises a delay locked loop frequency comparator(521) and a frequency selection logic(522). The delay locked loop frequency comparator outputs a frequency comparison signal by comparing the phase of the frequency divided signal with the phase of a phase delay frequency divided signal. The frequency selection logic outputs a selected value to the voltage controlled oscillator by selecting a frequency corresponding to the compared frequency comparison signal.
