20.500.12556/DKUM-66369 High resolution switching mode inductance-to-frequency converter with temperature compensation This article proposes a novel method for the temperature-compensated inductance-to-frequency converter with a single quartz crystal oscillating in the switching oscillating circuit to achieve better temperature stability of the converter. The novelty of this method lies in the switching-mode converter, the use of additionally connected impedances in parallel to the shunt capacitances of the quartz crystal, and two inductances in series to the quartz crystal. This brings a considerable reduction of the temperature influence of AT-cut crystal frequency change in the temperature range between 10 and 40 °C. The oscillator switching method and the switching impedances connected to the quartz crystal do not only compensate for the crystalʼs natural temperature characteristics but also any other influences on the crystal such as ageing as well as from other oscillating circuit elements. In addition, the method also improves frequency sensitivity in inductance measurements. The experimental results show that through high temperature compensation improvement of the quartz crystal characteristics, this switching method theoretically enables a 2 pH resolution. It converts inductance to frequency in the range of 85-100 nH to 2-560 kHz. inductance-to-frequency switching methods dynamic temperature compensation of circuit elements precision metrology induktanca frekvenca konverterji dinamična temperaturna kompenzacija elementov vezja preciznost metrologija senzorska stikala true true true Angleški jezik Slovenski jezik Znanstveno delo 2017-06-22 11:02:40 2017-06-22 11:03:31 2022-07-11 03:06:32 2019-07-11 15:45:05 2014 0 0 str. 19242-19259 št. 10 Letn. 14 2014 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1424-8220 621.31 10176278 18183190 10.3390/s141019242 1424-8220 URN:SI:UM:DK:ZKUBIDLE Sensors_2014_Matko,_Milanovic_High_Resolution_Switching_Mode_Inductance-to-Frequency_Converter_with_Temperature_Compensation.pdf Sensors_2014_Matko,_Milanovic_High_Resolution_Switching_Mode_Inductance-to-Frequency_Converter_with_Temperature_Compensation.pdf 1 2A5E55EB62B05F50E4C2B700A1418818 2ecbd09188e9034c277fe02608e2b74ffc63a66324b1cec5f0ebd2a5565c8398 483c6ef3-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112940 http://www.mdpi.com/1424-8220/14/10/19242/ 1 https://dk.um.si/Dokument.php?lang=slv&id=112939 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
