Patent ID: 8451968

Claim:
A phase-coupled clock signal generator comprising: a start-stop oscillator having an input for receiving a control signal to allow oscillation in response to a first value of the control signal and no oscillation in response to a second value of the control signal, characterized in that the start-stop oscillator is of a type whose generated frequency is adjustable by means of an applied adjusting value and in that the clock signal generator comprises control means for adapting the adjusting value in response to a difference between the generated frequency and a predetermined desired frequency; wherein the start-stop oscillator includes: a capacitor; a current source for charging the capacitor, in which the value of the current corresponds to the applied adjusting value; a discharge circuit for discharging the capacitor; a threshold circuit for switching on the discharge circuit in response to reaching a predetermined first voltage across the capacitor and for switching off the discharge circuit in response to a second voltage across the capacitor, and a stop circuit for switching on the discharge circuit in response to the second value of the applied reference signal.
