Abstract
An oscillator is temperature compensated by adjusting a slave oscillator with an error signal, that is produced by using the temperature of a reference oscillator to determine the frequency error of the reference oscillator, and then adjusting the frequency of the slave oscillator until its frequency coincides with an ambient reference frequency.
