  In this paper for the solution of the transformation "voltage-to-pulse" is proposed implemented in CMOS basis (technical process SGB25VD) structure based on high-frequency converter and comparator multiplexer with symmetrical hysteresis. Increasing the accuracy of the transformation achieved by the proposed method switching input voltages, excluding the through-analog switches. The results of computer simulation confirmed the effectiveness of the developed structure. Practical implementation of an analog-to-digital converter has shown that the proposed method of construction reduces the technological requirements for the components of the system-on-chip and increase its productivity.

  Requirements for methods of diagnosing design increases - they should make it possible to fully assess the performance of buildings, as well as being simple and mobile, to be used during the construction, operation, maintenance and reconstruction. This work is devoted to the realization of experimental and theoretical methods for vibration monitoring of structures and the analysis of the results. The objects of study are the reinforced concrete beams and slabs, and the subject of the study - the methods of vibration diagnostics, the principle of which is to detect changes in the construction of the main dynamic characteristics. Research has shown that damage to the structure can be detected by the methods considered, using a relatively small number of monitoring points and subject to change only the fundamental mode of vibration.
