Abstract
A generator producing a clock signal whose frequency depends on a control voltage includes a comparator for comparing a period of the clock signal with a desired period, and for providing at least one first control signal based upon the comparison. The generator includes a sampler circuit for sampling the first control signal, and for producing a first sampled control signal. The generator also includes a voltage generator for providing the variable control voltage as a function of the first sampled control signal.
