Apparatus and method for generating an oscillation signal, mobile communication systems and mobile device

Abstract:

An apparatus for generating an oscillation signal is provided. The apparatus includes an input configured to receive a first reference oscillation signal, and a phase detector circuit configured to determine a phase drift of the first reference oscillation signal with respect to a second reference oscillation signal. Further, the apparatus includes a phase shifter circuit configured to generate the oscillation signal based on the first reference oscillation signal and a control signal. The control signal is based on the phase drift and a frequency control signal comprising control data for the phase shifter circuit for adjusting a frequency of the oscillation signal to a desired frequency.
