Harnaha V. Direct current push-pull amplifiers for multy bit ADC and DAC with self calibration

Purpose of the research is to improve static and dynamic characteristics of push-pull current amplifier; the object of research - the processes of static and dynamic errors in the push-pull DC amplifiers, as well as ways to reduce these errors; the subject of study is the structural and functional organization of the symmetrical push-pull DC amplifier, as well as their static and dynamic characteristics; research methods: basic theory of electronic circuits and elements of the theory of errors, the mathematical apparatus of special functions, computer simulation, scientific novelty: there had been pioneered the method of structural and functional organization of the symmetric push-pull DC amplifier, with improved static and dynamic characteristics, which is based on the introduction of Peaking selective feedback in counterphase channels; the method for parametric compensation of non identity static characteristics of intermediate stages of DC amplifier got further development, built using the transistors with different conductivity type. The main scientific results and practice recommendation were introduced in National Radio Company of Ukraine, Ltd "SI Technology Instruments" (Russian Federation) and at the department Computing Equipment of Vinnitsa National Technical University. The application sphere enterprises microelectronic industry of Ukraine.
