ABSTRACT:
A digitally temperature-compensated oscillator has an oscillator for producing a frequency signal, a regulator for regulating the frequency of the frequency signal, and a detector for detecting ambient temperature and producing a corresponding temperature signal. A processor processes the temperature signal with reference to the frequency signal to produce processed temperature data. A memory stores compensation data effective to regulate the frequency of the frequency signal. A controller operates according to the temperature data to retrieve corresponding compensation data from the memory for controlling the regulator according to the retrieved compensation data to regulate the frequency of the frequency signal.
