<p>There is provided an oscillator arrangement for generating a clock signal. The oscillator arrangement comprises a current controlled oscillator, a frequency to voltage converter, and an operational amplifier. The oscillator arrangement is connectable to a supply voltage source. The current controlled oscillator is adapted to generate a clock signal based on a control voltage signal, wherein the generated clock signal is supplied to the frequency to voltage converter. The frequency to voltage converter is adapted to generate an output voltage signal based on the generated clock signal and based on the supply voltage signal. The operational amplifier is adapted to receive the output voltage signal as a feedback signal at a first input terminal and to receive a reference voltage signal at a second input terminal, the reference voltage signal being generated from the supply voltage signal. The current controlled oscillator is adapted to be controlled based on an output signal of the operational amplifier, wherein the output signal of the operational amplifier provides the control voltage signal to the current controlled oscillator in order to control the frequency of the clock signal.</p> |
