Reshetnik O. High-productive ADC with changing tact durations of successive approximation with weight redundancy

The object of investigation is process of highly productive fast analog-to-digital conversion with variable sensitivity of comparison operation of analog signals and with variable tact durations of successive approximation with weight redundancy; Methods of investigation – theory of analog-to-digital conversion with weight redundancy, theoretical backgrounds of electronic circuits, theory of linear integral circuits, theory of state machines, theory of measurements, theory of probability, mathematical analysis, theory of object oriented programming; theoretical results – new method of increasing of productivity multibit successive approximation ADC with weight redundancy with help of using variable tact durations of fast successive approximation, improved mathematical models of static and dynamic errors of fast successive approximation with weight redundancy based on balance equations, improved mathematical model of transient processes of compression operation, improved method of DAC building with weight redundancy; practical results – recommendations for development of highly productive ADC with variable tact durations are offered, recommendations for building of highly productive SAR ADC with weight redundancy are offered, structure, functional and electronic circuits of ADC with variable tact durations are developed, highly productive ADC with variable tact durations are built. Level of introduction - the dissertation results are introduced on state company “Ukrkosmos” (Kyiv), on Institute of electronics and communication of Ukraine science academy (Kyiv), in process of learning on computer science chair in Vinnitsya national technical university in disciplines “Computer electronics”, “Linear integral circuits”, “Analog and digital equimpent”.
