Abstract:
A clock-signal generator for generating a clock signal at a clock-signal generator output, the clock-signal generator comprising:a discrete timing oscillator that is clocked with an input clock signal and that generates a periodic digital DTO output signal, a phase displacement calculation unit for calculating the phase displacement between a signal phase of the DTO output signal and a signal phase of a most-significant-bit of the DTO output signal, the phase displacement calculation unit including a digital derivative unit that generates a clock pulse at each signal edge of the most-significant-bit of the DTO output signal, and a phase displacement reduction unit for reducing the phase displacement between the signal phase of the DTO output signal and the signal phase of the most-significant-bit of the DTO output signal as a function of a calculated phase displacement provided by the phase displacement calculation unit.
