| Summary: | This article proposes a cost efficient and easy to implement frequency stabilization method orientated
toward communication systems operating in an extensive temperature range, as the automotive or the
aerospace applications. The proposed solution uses off-the-shelf components and it is optimized for
very low power consumption. The novelty of this article is represented by the introduction of the
barium strontium titanate capacitor for quartz crystal oscillator active frequency stabilization.
After the design was completed, the performances were evaluated and compared to the ones of the
uncompensated oscillator. Experimental results confirmed the suitability of the proposed design,
achieving 35 times better frequency stability within variable temperature conditions, whereas
the power consumption is maintained below 6mW. |
