Abstract
An electronic device may include a voltage controlled oscillator (VCO) and a temperature sensor. The electronic device may also include a controller configured to cooperate with the VCO and the temperature sensor to determine both a temperature and a frequency error of the VCO for each of a plurality of most recent samples. Each of the most recent samples may have a given age associated therewith. The controller may also be configured to align the temperature, the frequency error, and the given age for each of most recent samples in a three-dimensional (3D) coordinate system having respective temperature, frequency error and age axes. The controller may also be configured to estimate a predicted frequency error of the VCO based upon the aligned temperature, frequency error, and given age of the most recent samples.
