Holyaka R. Analog bipolar integrated circuits for sensor technology

Subject of research: elements and semiconductor integrated circuits multielemental structures and also based on them sensor integrated devices. The aim of the research: the developments of constructing and functional principles, circuit and constructional basement for creating specialized series of solidstate analog integrated circuits for the new generation sensor engineering. Methods of research: math and computer simulation of physical process and electronic circuits, the devices parameters measurements. Theoretical and practical results, novelty: general-purposes models of primary transducers for sensor devices using "P-SPICE" software, correction principle of the intellectual magnetic sensor devices, that is based on the analysis of transducing parameters by integral and differential signal components and it is realized at functionally integrated magnetometric transducer; synthesis methods of transducing function on solidstate analog multiunit multipliers, which have such a peculiarity as no multitransducement "voltage-current-voltage" that provide the minimum of high precision resistors, energy consuming and the extension of the signal range; hyperbolical tangent function appliance in the analog composers; principles of analog composers to be controlled by the external signals; solidstate analog thermal compensator parameters synthesis by multiplication temperature coefficient by the circuit that forms exponential function having the adjustable exponent; engineering principles and elements of thermostatically controlled sensor devices having selfheating primary transducers; differential principle of heattransfer channel of solid state integrated circuit using heattransfer fenomena which is the base for new multifunctional component - heat controlled operational amplifier; the further development of sensor integrated circuits theory supplied by signal line and automatic switch of sensor devices between the normal function and waiting mode, that simplifies sensor devices appliance and minimizes energyconsuming. Scope of application: solidstate integrated circuits, sensors.
