THE SILICON MAGNITOSENSITIVE ELEMENTS AND INTEGRAL CIRCUITS ON THE BASE KMOP OF THE CONSTRUCTIVE-TECHNOLOGICAL BASIS

The purpose of the work: the development and complex investigation of the constructions and methods of formation of the silicon magnitotransistor structures (MTS) and magnitosensitive circuits (MSC) on the base KMOP of the constructive-technological basis. The object of investigation: the magnitotransistor structures on the base of the bipolar two-collector transistor (BTT), MOP of the Hall's element, two-flow MOP of magnitotransistor and KMOP structure, and microflow KMOP MSC with linear, threshold and frequency type of the output signal. The physico-mathematical model of the two-flow MOP of the magnitotransistor and the design program on its base, considering the peculiarities of the construction and physical structure, have been developed. The results of the investigation of the magnitotransistor structures of the mode of operation and temperature have been received. Developed and made has been the set of the microflow MSC with widened functional possibilities, allowing to perform the MSC tuning for the operation in a wide range of magnetic fields. The developed magnitosensitive circuits with linear output have been used for creation of the units of measure of the magnetic field and teslameter of the Mayak type, which has allowed to receive the high values of the magnetosensitivity (above 20 V/Tl) with the little current consumption (0,5 mA maximum). Using the bipolar two-collector transistors in the construction of the magnetic flaw detector has allowed to increase its magnetosensitivity by the order and to improve the solving ability. The MTS and the MSC can be used in the design of the robototechnical complexes, in the avia- and automobile electronics; in measuring technique, in flaw detectors, in the contactless current transmitters, in the electric motor control devices, in the automatics regulation contoursAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
