Abstract:	The paper deals with a reduction of static frequency vs. temperature (f-T) dependency of digitally generated sinusoidal signals. The f-T dependency reduction is based on a self-temperature-sensing of a quartz crystal in dual-mode crystal oscillator, which produces the reference clock. We have proposed a digital oscillator, which automatically compensates the f-T dependency of its sampling clock over a wide range of operating temperatures. Numerical accuracy limitation of the oscillator due to finite word-length arithmetic is also analyzed in this article.
