Learning Goals

To obtain basic skills in analysis and conception of analog electric circuits. To understand the physical principles of solid state devices used in electronic circuits. To know the limitations and non-ideal behavior of each semiconductor component.

Contents

1. Introduction to Circuit Analysis. Basic concepts revisited.


Fundamental electric units. Electric potential. Electric voltage. Current intensity. Electromotive force. Ohm’s Law. Resistors in Series and Parallel. Direct current circuits.


 


2. Semiconductors


Semiconductor materials. Intrinsic and Doped semiconductors. Type N and type P semiconductors. PN junction. Potential energy barrier. Direct and Inverse Polarization.


 


3. Diode


The ideal diode. Characteristic curve. The real diode. Characteristic curve. Approximate models. Small-signal model e its applications. Rectifier circuits.


The Zener diode, the tunnel diode and the light emitting diode (LED). Applications.


 


4. Transistors


Bipolar Junction Transistor (BJT)


Characteristic curves. Operation regions. Polarization schemes. Typical configurations: common emitter, common base, and common collector. Characteristics. Small signal analysis. Applications.


Field Effect Transistor


The Junction FET (JFET). Characteristic curves. The Metal-Oxide Semiconductor FET (MOSFET). Characteristic curves.


5. Operational Amplifiers


Real and ideal characteristics. Analysis of OpAmps with feedback.


Linear circuits with OpAmps: inverting configuration, non- inverting configuration, voltage follower, current-voltage and voltage-current converters, differential amplifier.


Operational circuits with OpAmps: inverting and non-inverting summer, integrator and differentiator.


Nonlinear Circuits with OpAmps: comparators, rectifiers and limiting circuits.

Teaching Methods

The teaching method is based in theoretical, practical and laboratory classes. The student should have experimental contact with the various components and instruments used in analog electronics.

Assessment

The assessment is based on 2 parts: Theoretical (70%) and Laboratorial (30%)


Assessment elements are graded using the interval [0,20].


The theoretical part can be achieved either through 2 Tests or a Final Exam – Minimum grade 9.5



  • [F1] Test 1 – Minimum grade 8.0 (35%)

  • [F2] Test 2 - Minimum grade 8.0 (35%)

  • [Ex1] Final Exam 1 (70%)

  • [Ex2] Final Exam 2 (70%)


 


The Laboratorial part has minimum grade 9.5



  • [L] Laboratory (30%)


 


[NF] Final Grade: NF = Max{(F1 + F2)/2; Ex1; Ex 2}×0.7 + L×0.3


 


If NF>= 9.5 : Approved


If NF< 9.5 :   Failed
