    • A voltage-controlled oscillator (VCO) control circuit, used for controlling a VCO to process phase locking procedure after receiving a frequency locking signal, comprises an operating frequency controller and a judgment unit. The operating frequency controller, coupled to the VCO and the judgment unit, generates one of a first control code and a second control code to the VCO. The judgment unit, coupled to an input end of the VCO, generates a phase locking signal according to a voltage control signal inputted to the VCO. When the operating frequency controller receives the frequency locking signal, the operating frequency controller generates a first control code to control the VCO to switch from a first candidate VCO curve to a second candidate VCO curve. When the operating frequency controller receives the phase locking signal, the operating frequency controller generates a second control code to control the VCO to switch from the second candidate VCO curve to the first candidate VCO curve.
    • 用于控制VCO在接收到频率锁定信号之后处理相位锁定过程的压控振荡器(VCO)控制电路包括操作频率控制器和判断单元。 耦合到VCO和判断单元的工作频率控制器产生VCO的第一控制码和第二控制码之一。 耦合到VCO的输入端的判断单元根据输入到VCO的电压控制信号产生锁相信号。 当工作频率控制器接收到频率锁定信号时,工作频率控制器产生第一控制码以控制VCO从第一候选VCO曲线切换到第二候选VCO曲线。 当工作频率控制器接收到相位锁定信号时,工作频率控制器产生第二控制码,以控制VCO从第二候选VCO曲线切换到第一候选VCO曲线。
