Analogical Systems (SEAN 2)
The overall objective of the course is that the student acquires a broad view of analog design aspects that allow both design analog circuits and systems, and understandelectronic equipment used in communications and instrumentation. Especially, the student will able to design with Operational Amplifiers and other analog integrated circuits as analog multipliers, linear voltage regulators and switched, VCOs, PLLs, etc.. Additional emphasis will be placed on the ability to assess the noise in the analog signal processing knowledge of the main limitations and consistent care when analog design.
The exact content of the program is adapted to the student profile To do this, at the beginning of course there is an analysis of the average profile and interests of reinforcement and intensification, indicated by attendees in the first class. In any case, the subject is divided into two parts, but by modulating the intensity of each subject based on the profile of students:
Part One: Concepts horizontal applications (~ 20 h)
• Sensors and Electronic signals in the interaction with the real world. Equivalent circuital real signal sources. Signal / noise ratio and management (conditioning) appropriate electronic signals as appropriate. Amplifiers required type and its limitations.
• Operational Amplifiers (AO) integrated. Basic structure and concrete according to the types and use of AO's current. Features, benefits and limitations of the AO's current. Basic Employment negative feedback (RN) in the AO's design. Easements circuital and practical design aspects.
• Use feedback advanced in design with AO's. Positive feedback and design possibilities offered. Frequency dependent feedback signal: RN instability or loss and compensation. Simultaneous feedback (positive and negative) and their use in analog design. New design aspects of Global Negative Feedback (RGN) and Balanced (GERD).
Second part: Getting more specific application (~ 20 h)
• Systems for handling weak signals. Types of electrical noise. AO's design for low noise performance in the system.
• Practical aspects of printed circuit (Seebeck effect, leak guard techniques, etc.). Noise reduction techniques in systems.
• Systems for analog signal processing. Integrated multiplier circuits. Features and employment according to the design requirements. Application Communications and Instrumentation: practical examples of current use circuits.
• Systems for signal acquisition and actuation. A / D Conversion High resolution: Oversampling and generators using "dither". Related noise reduction.
Data Acquisition Systems for PC. Integrated Circuits and Systems Drive (Smart Power IC's).
• Power amplifiers: design and thermal constraints.
