Circuit arrangement for controlling the control voltage for a clock generator constructed as voltage-controlled oscillator |
摘要 |
The series-connected transistors connected to the outputs of a phase detector, which are used for charging or discharging a capacitor, are constructed as constant-current sources. As a result, the capacitor is charged or discharged with a constant current, the amount of current being proportional to the driving time independently of the state of charge of the capacitor.
