This article introduces a new method for nano-Henry inductance measurements atthe frequency of 4.999 MHz with a single quartz crystal oscillating in the switching oscillating circuit. The real novelty of this method, however, lies in a considerable reduction of the temperature influence of AT-cut crystal frequency change in the temperature range between 0 °C and 50 °C through a switching method which compensates for the crystalćs natural temperature characteristics. This allows for the compensation of any influences on the crystal such as the compensation of the non-linear temperature characteristicsand the ageing of both the crystal and other oscillating circuit elements, as well as the reduction of the output frequency measurementerrors with the help of an additional reference frequency. The experimental results show that the switching method greatly improves the measurement of small inductance changes in the range between H and nH, allowing as a result high-precision measurements (~0.35 fH) in this range.
