Modélisation Non Linéaire des Oscillateurs à Quartz, Développement d'un Logiciel de Simulation

Abstract : In the past, the ultra-stable oscillators
development for space and military applications
was essentially based on practical and
experimental knowledge of specialists. A more
rigorous approach was introduced to improve
the design and the optimization of the ultrastable
oscillators (particularly quartz oscillators).
This thesis follows a series of works within the
framework of several contracts between the
LPMO and the CNES concerning the modelling
of quartz oscillators. The aim of our work is to
provide the CNES a software (called ADOQ)
which permits the design of high quality quartz
oscillators. The software developed for circuit
with high quality coefficient is based on an
original method of calculation called Grand-Sinus method. ADOQ software enables us to
compute the operating condition with high
degree of accuracy in frequency, amplitude,
drive level of the resonator in steady state,
transient, amplitude and phase noise spectra.
The oscillator sensitivity to the variation in the
components can be evaluated. A very few
industrial software can provide this kind of
information and generally they are obtained
with tradeoff modifications and adaptations.
This work is completed by experimental
validation of the Grand-Sinus method and a
good agreement between the simulation results
and the measurement on high quality coefficient
quartz crystal oscillators has been
