A digitally controllable oscillator includes an oscillation generation
means and an oscillator control, wherein the oscillator control comprises
two digital/analog converters whose output signals are combined by a
combiner in order to generate an analog input signal into the oscillation
generation means. The second digital/analog converter is implemented in
order to provide, in response to a digital increment in its digital input
signal, a difference in the output signal of the second digital/analog
converter which is smaller than a difference in the output signal of the
first digital/analog converter when the first digital/analog converter is
pulsed with the digital increment in its digital input signal.
