Sistemas Electrónicos de Computadores

Objectives

To develop the knowledge concerning the electronic feedback circuits. To teach the basic knoledge of the analog and digital filters and memories. To teach how to use microcontrollers for implementing simple electronic systems.

Syllabus

1. Feedback and Stability: Feedback topologies. Linear two-ports. Stability: the Nyquist plot, the effect of feedback on the amplifier poles, gain and phase margins. Compensation. 2. Analog Filters: Project of Butterworth and Chebyshev filters. Frequency transformations. Realization of active filters by direct simulation (GIC). Biquad sections. 3. Oscillators: The Barkhausen criterion. Amplitude and frequency stabilization of the oscillations. Oscillator circuits: Wien-Bridge, Phase Shift and LC and Relaxation oscillators. Applications. 4. Digital filters: signal sampling. IIR and FIR filters. Realization of digital filters. 5. Digital Systems: ROM, EEPROM, SRAM AND DRAM memories. 6. Embedded Systems. Embedded systems electronics. Interface between the microcontrollers and their external components. Bluetooth, ZigBee, Wi-Fi and IoT. Project, implementation and test of advanced electronic embedded systems.

Prerequisites

Knowledge of the basic electronic devices and of elementary circuit analisys. The students should have attended successfully the CU Electronic Circuits in order to have enough knowledge for a suitable assimilation of the subjets taught is Electronic Systems.

Cross Competence Component

In the CU Electronic Systems the developing of the student soft skills is promoted, by means of the classes typology (TP and L), where the students will have to solve individual problems, which encourages the critical and innovative thinking, and also they will have to execute group tasks, which encourages interpersonal skills. The CU own structure, by requiring just 9 weeks to executed it, leads to the development of intrapersonal skills (as, for instance, the self discipline). The Soft Skills evaluation component is essentially integrated in the Laboratory grade component, which represents 50% of the final grade, corresponding a percentage of about 5% of the final grade

Laboratorial Component

Three or four works with hardware and software components, covering the areas of Feedback, Analog Filtering, Oscillators, Digital Filtering and microcontrollers

Programming And Computing Component

Students should use software tools in the laboratory works. These tools are estimated to include the simulation programs SPICE and MATLAB+Simulink. The Programming and Computing evaluation components are integrated in the Laboratory grade component, which represents 50% of the final grade, corresponding to a percentage of about 5% of the final grade.

Ethical Principles

All members of a group are responsible for the group’s work In any assessment, every student shall honestly disclose any help received and sources used. In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
