Method for dynamically tuning the clock frequency of an oscillator and corresponding oscillating system

An oscillator system comprising:

• an oscillator block having a plurality of inputs and outputting a clock signal;
• a multiplexer receiving the clock signal and a reference clock signal and outputting the reference clock signal during a calibration mode;
• a frequency divider block receiving an output of said multiplexer and outputting a divided clock signal;
• a tuning block including an integrator for receiving the divided clock signal and a first reference value, and for integrating the divided clock signal using the first reference value, and outputting a comparison signal;
• and
• a control block coupled to said tuning block, said control block receiving the comparison signal and comprising
• a configuration block for producing a plurality of outputs for the corresponding inputs of said oscillator block, and
• an Up/Down counter having outputs applied to said configuration block.

A method for dynamically tuning a clock frequency from by an oscillator comprising at least one oscillator block, the oscillator block having a plurality of inputs and outputting a clock signal, the method comprising:

• dividing the clock signal produced by the oscillator block with a frequency divider block;
• integrating the divided clock signal from the frequency divider block into an electric magnitude signal with a tuning block having an integrator using a received first reference value;
• comparing the electric magnitude signal with a reference signal in the tuning block;
• and
• applying a signal from the comparing to a control block comprising an Up/Down counter and a configuration block for the oscillator block, the applying for regulating values of the plurality of inputs.
