Mishan V. Controlled quartz oscillating devices with low Q-factor load

The thesis is devoted to questions increasing of accuracy and extending of the functional possibilities for the controlled quartz oscillating systems (QOS) with low Q - factor load. The QOS mathematical model is proposed, which established an analytical connection between the characteristics of the oscillating system and the parameters of elements for low Q-factor load. The questions of analysis and synthesis are considered for the controlled frequency - compensated QOS with low Q - factor load and their features of using as the measuring transformers of the physical qualities. The examples are proposed for using of this type QOS for telecommunication measuring systems and devices of the radioengineering as for the sensory network on the base of the controlled QOS with low load and the MEMS elements, one-chip controlled generator with low Q-factor resonator, the dielectric measuring device of the matter humidity with a describe structure.
