A digitally temperature-compensated crystal oscillator

IEEE Journal of Solid-State Circuits, 2000
The base frequency of oscillators used in the Global System for Mobile Communication (GSM) network or Global Positioning System (GPS) receiver applications needs to be very stable with respect to temperature and supply-voltage variations. One approach to obtain extremely good frequency stability is the use of oven-stabilized crystal oscillators.

On Tire Monitoring Systems Temperature Compensation

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">Direct type [<span class="xref">1</span>] Tire Monitoring Systems supervise tire internal inflating pressure. The authors previously proved that Tire Monitoring must be focused on the tire (i.e.: vehicle) dynamic behaviour [<span class="xref">2</span>]: the real aim of the supervising action.

Temperature Compensated Piezoelectric Materials

1979
Abstract : From the electrostriction measurements on SBN crystals, it was found that the fourth order electrostrictive coupling terms are not adequate to fully describe the paraelectric phase above Curie temperature, and hence six rank coupling terms are needed; the electrostrictive coupling terms do not change markedly with cation substitution ...

Compensation of Temperature Effect for LVDT Transducer

Journal of Circuits, Systems and Computers, 2018
In this paper, a circuit technique to compensate the temperature effect in the output signal of the linear variable differential transformer (LVDT) is presented. The realization technique is based on the proposed feedback configuration to minimize the active component used in the circuit.

An Ultralinear Stress-Compensated Temperature Sensor

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1987
Stress-compensated quartz resonators having ultralinear frequency-temperature responses (NLSC cuts) have been discovered. They consist of doubly rotated cuts in which the orientations, defined in terms of the polar angles bo and eo, lie on a locus where the second- order temperature coefficients of frequency are zero in the range of bo = 20" f 2" and ...

Temperature compensation in the mammalian cell cycle

Experimental Cell Research, 1982
Abstract Random and synchronous V79 cells were shifted from 37.5 °C to temperatures between 29 ° and 41 °C. Intermitotic time determinations of random cultures showed an increase in generation time and a broadening in the distribution of generation times in cells whose cycle spanned the temperature shift, but only a slight increase in generation time

Calorimetric measurements with compensating temperature control

2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), 2017
Measuring the dissipated power of fast switching semiconductors or magnetic components with low power factor makes high demands on the accuracy of the measurement equipment. Calorimetric measurement methods represent a possible solution for this problem but are considered as being too time demanding.

Temperature Compensation Techniques

1958
Before going into a discussion of temperature compensation techniques, it is important to consider for a moment the kind of information a strain gage can provide under constant or variable high temperature conditions. Under constant temperature conditions, it is possible to allow time for all specimen parts to come to the same temperature before an ...

Temperature compensation in indicating and recording instruments

Journal of the Institution of Electrical Engineers - Part II: Power Engineering, 1945
One cause of errors in indicating and recording instruments is their use at a temperature other than that at which they were calibrated. Most of the physical properties of materials on which the performance of an instrument depends, vary to a greater or less degree with temperature.
