Reducing SAW Oscillator Temperature Sensitivity with Digital Compensation,
Abstract
Generation of precise frequencies by means of crystal oscillators is an important electronics function. Recently, surface acoustic wave (SAW) oscillators such as the one illustrated in Figure 1, have shown themselves to be a particularly cost effective implementation of this function. However, a problem exists in maintaining frequency stability over a wide temperature range; a problem shared to a lesser degree by bulk oscillators. A number of techniques have been proposed to compensate for this temperature sensitivity for bulk and surface acoustic wave oscillators. It is the purpose of this paper to describe a simple and effective means for digitally compensating for the temperature sensitivity of a SAW oscillator.
