Device and method for regeneration of a clock signal, apparatus and method for converting a clock signal into a zero-mean signal

Apparatus for regenerating a jitter having clock signal, comprising: means (100), which has a switched-capacitor integrator (10), for converting the clock signal into a signal having at least one edge jitter, and means (300) which is connected to an output of the conversion means (100) for determining an offset voltage of the signal, characterized, in that of the switched-capacitor integrator (10) comprises a controllable reference voltage source (Vref) and / or a controllable capacitor (5), and said determining means (300) to the controllable reference voltage source (Vref) and / or to the controllable capacitor (5) is connected.
