摘要： 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.

摘要： A sigma-delta modulator is supplied with a data word and includes a first and at least one further modulation stage, each having at least two adders. The adders in the first modulation stage process a low-significance component and a delayed more significant component of the data word and provide a result word and a carry at their respective outputs. The adders in the at least one further modulation stage process a low-significance component and a more significant component of the result word and provide a further result word and a carry at their respective outputs. The low-significance component and the more significant component of the result word are provided to the further modulation stages with an unvarying delay. A bit stream is derived from a carry from final instances of the at least two adders in the first modulation stage and in the further modulation stage respectively.

摘要： The invention is directed to a resonant circuit having a frequency-determining element which has at least one switchable frequency-changing element connected in parallel therewith. The frequency-changing element has two series-connected transistors whose control connections are connected to a node that receives a fixed potential. First connections of the two series-connected transistors are connected to one another and also to a control input for a control signal for switching the frequency-changing element of the resonant circuit. The invention keeps the control voltage for the two transistors at a higher potential than the threshold voltage for the transistors. This reduces a parasitic capacitance in the two transistors during operation.
