Abstract
A digitally controlled oscillator device includes a programming input, a selection input and an oscillator core with a first capacitive element which is frequency determining and programmable. The first capacitive element is coupled to the programming input that receives a first data word by which an oscillating frequency of the oscillator device is programmed with a predetermined frequency step size. The oscillator device further includes a selection unit for selecting a mode which is coupled to the selection input that receives a mode selection signal. The mode is selectable from a plurality of modes depending on the mode selection signal and each mode from the plurality of modes is characterized by a predetermined frequency step size. The digitally controlled oscillator device also includes a deattenuation amplifier.
