I. The principles of A/D and D/A conversion and its basic specifications, major architectures, and circuit components (building blocks); various issues with A/D and D/A converters and their relationships with performance; and delta-sigma modulation technology and the process of delta-sigma A/D and D/A converters.
II. Students will understand the basic operating principles of PLL and further their building blocks (voltage-controlled oscillator, phase comparator, charge pump, frequency divider, and loop filter) and by deriving and analyzing transfer functions.
III. Students will understand the basic functions and types of power converter circuits and will learn about regulators and bandgap reference circuits. They will also understand AC-to-DC and DC-to-DC converters.
Most of the signal processing in modern electronic instruments are done with digital circuits, however, the signals to work with in the real world are analog. For this reason, analog-to-digital (A/D) converters and digital-to-analog (D/A) converters have become important circuits. Phase locked loops (PLLs), which generate signals of a specific frequency, and power converter circuits, which supply power to the entire electronic instrument, are necessary in electronic instruments, and since it is technically difficult to replace everything with digital circuits, analog circuit technology is being used.
By the end of this course, students will be able to explain the principles and basic performance of applied analog electronic circuit technology: A/D and D/A converters, PLLs, and power supply circuits. The goal is for students to reach a level where they can understand the spec sheets of such circuits and create a basic design based on the intended performance.
