The new method of improving frequencypullability uses inductance to compensate for quartz stray capacitances. To this end, a special AT fundamental quartz crystal working near the antiresonance frequency is selected. By modifying its equivalent circuit with load inductance and series tuning capacitance, the magnetic sensing of the circuit can be highly improved. The experimental results show that the new approach using the quartz crystal stray capacitance compensation method increases the frequency pulling range (from \u2245 2 kHz\/mH to \u2245 600 kHz\/mH) by \u00d7 300 depending on the type of oscillator, making possible the measurement of nano-magnetic changes.<\/jats:p>","DOI":"10.3390\/s100403954","type":"journal-article","created":{"date-parts":[[2010,4,20]],"date-time":"2010-04-20T10:11:27Z","timestamp":1271758287000},"page":"3954-3960","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Greatly Improved Small Inductance Measurement Using Quartz Crystal Parasitic Capacitance Compensation"],"prefix":"10.3390","volume":"10","author":[{"given":"Vojko","family":"Matko","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, University of Maribor, Smetanova 17, 2000 Maribor, Slovenia"}]},{"given":"Karel","family":"Jezernik","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, University of Maribor, Smetanova 17, 2000 Maribor, Slovenia"}]}],"member":"1968","published-online":{"date-parts":[[2010,4,20]]},"reference":[{"key":"ref_1","unstructured":"Dorf, R.C.
