Voltage controlled oscillator

An electronic system for producing an oscillating signal, comprising:

• a first circuit having an input for converting a parameter that affects the frequency of the oscillating signal to a voltage that will not cause a change in the frequency of the oscillating signal even though the parameter has changed in value,
• wherein the first circuit comprises an execution engine coupled to compare the parameter to a table of parameter values and corresponding set of frequencies to derive a compensated frequency near a nominal frequency value and to associate the nominal frequency value to the voltage;
• a summing node for adding the voltage to a scaled, user-defined input voltage according to a predefined ratio;
• and
• a second circuit adapted to produce the oscillating signal controlled by the summing node output.

A method for producing an oscillating signal, comprising:

• converting a parameter that affects the frequency of the oscillating signal to a voltage that is corrected by a change of the parameter,
• wherein converting comprises:
• comparing the parameter to a table of parameter values with corresponding frequency values;
• deriving a compensated frequency near a nominal frequency value;
• and
• associating the nominal frequency value to the voltage;
• adding the voltage to a scaled, user-defined input voltage according to a predefined ratio;
• and
• producing the oscillating signal having a frequency that is controlled by the added voltages.
