“…The frequency-temperature response is mainly caused by the pyroelectric effect of the piezoelectric conversion components (quartz crystals) and polarity change (Ferrari et al, 2004;Schön et al, 2001). In the range of −200-200 • C, the frequency-temperature characteristics f (t) of all quartz resonators can be precisely expressed as the formula (Tzou and Ye, 1996;Galliou and Mourey, 2001):…”

“…It has been said that the greatest contribution to the change in frequency makes a change in temperature. The effect of temperature on the frequency of the reference oscillator is determined by the temperature-frequency characteristics g(t o ) [7,8], an example of which is shown in Fig. 2.…”

This article discusses regularity between the temperature fluctuation of environment, in which operates the transmitting device, and a random frequency shift of a carrier. Shows how frequency stability over temperature of reference oscillators of transmitting devices influences the probability of packet loss as a result of collisions in asynchronous radio system without feedback. Particular solutions for the uniform and Gaussian distribution of random frequency shift are presented.

“…In such case, although the temperature gradient into the silicon still depends on the ambient temperature, the mean temperature remains equal to 80 • C. The relationship between the silicon temperature and the ambient temperature can actually be electronically compensated [32]. This compensation consists in adjusting the set temperature as a function of the ambient temperature (measured by a second sensor at T amb , for example or by monitoring the consumed power) instead of maintaining it constant (Fig.…”

International audienceThis paper describes a study of the thermal behaviour of fully packaged Caesium vapour cell developed in the framework of the European collaborative research project called "MEMS atomic clocks for timing, frequency control and communications (MAC-TFC)". This cell, along with various electronic and optical components, is embedded in a Low Temperature Co-fired Ceramics (LTCC) structure, in order to build a compact MEMS-based atomic clock. Functioning of such atomic clock depends on inner and outer environment of the Cs vapour cell, including parameters such as pressure and temperature of buffer gas. This paper is then devoted to study the thermal behaviour of a fully LTCC-packaged Cs vapour cell according to the ambient temperature change when it is locally temperature controlled. Simulations have been carried out by using analytical modelling and finite element based softwares. Different solutions concerning the LTCC structure such as bridges/suspensions, vacuum environment, metallic coating, as well as the optimal positions of the temperature-control elements have been investigated. Finally, preliminary experiments based on a prototype resulting from this study are presented and an additional solution based on the dynamic adjustment of the set temperature as a function of the ambient temperature is proposed
