1. An electronic device comprising:

  • a voltage controlled oscillator (VCO);

    a temperature sensor; and

    a controller configured tocooperate with said VCO and said temperature sensor to determine both a temperature and a frequency error of the VCO for each of a plurality of most recent samples, each sample having a given age associated therewith,align the temperature, the frequency error, and the given age for each of the plurality of most recent samples in a three-dimensional (3D) coordinate system having respective temperature, frequency error and age axes, andestimate a predicted frequency error of said VCO based upon the aligned temperature, frequency error, and given age of the plurality of most recent samples.
