    • A low-pass passive filter is inserted in the phase locked loop of a voltage-controlled oscillating circuit having a varactor diode. The filter has a first resistor, a capacitor and a second resistor connected in that order and the blocking characteristics of the filter are changed in accordance with a selected value of the second resistor. A push-pull output circuit in which the upstream transistor is connected directly to the supply voltage line receives the signal from a phase comparator circuit (which is indicative of the result of phase comparison) and outputs it to the low-pass passive filter. The low-pass passive filter controls the terminal voltage of the varactor diode in accordance with the terminal voltage of the capacitor and the value of the second resistor is selected depending on the desired blocking characteristics of the filter.
    • 在具有变容二极管的压控振荡电路的锁相环中插入低通无源滤波器。 滤波器具有按照该顺序连接的第一电阻器,电容器和第二电阻器,并且滤波器的阻塞特性根据第二电阻器的选定值而改变。 其中上游晶体管直接连接到电源电压线的推挽输出电路接收来自相位比较器电路的信号(其表示相位比较的结果),并将其输出到低通无源滤波器。 低通无源滤波器根据电容器的端子电压来控制变容二极管的端子电压,并且根据滤波器的期望的阻塞特性来选择第二电阻器的值。
