Аннотация. Качество подготовки специалиста во многом определяется реализуемой программой его обучения и, в частности, главным докум ентом этой программ-учебным планом высшего учебного заведения. Процесс подготовки специалистов, отвечающих современным запросам, влечет за собой необходимость непрерывного совершенствования учебных планов и как следствие применения средств автоматизации для их составления и корректировки. В статье рассматриваются вопросы целесообразной организации автоматизированной информационной системы «Учебно-методический комплекс кафедры» с учетом личностно-ориентированного характера современных образовательных программ.-Библ. 3 назв.
The paper architecture CMOS ADC with digital forecasting an inlet of the analog signal and signal transformation errors sectional ADCS from analog to howl convolution. It is shown that 12-bit CMOS ADC with project standards 0.18 micron provides high accuracy and speed of conversion to 600...1000 million samples/s when operating in hard conditions.
The formulated optimal requirements sectional bezkontaktni DAC. Considered are the main technological and frequency limitations sovovych DAC with low power consumption. Suggested 4-bit binary-weighted Zogby differential DAC architecture analogue circuit.
Considered architecture CMOS ADC with digital forecasting input analog signal and converted education error signal sectional ADCS from analog convolution. It is shown that 12-bit CMOS ADC with project standards 0.18 micron provides high accuracy and speed of conversion to 600...1000 million samples/s when operating in hard conditions. Noted that through simple modifications considered architecture can increase the bit CMOS ADC to 14 bits.
Proposed amplifier with capacitance inputs and internal resistor feedback to adjust gain factor. The obtained characteristics (SFDR > 100 dB SNR > 120 dB) provide 16-bit accuracy, necessary for creation of a pipelined ADC similar capacity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
