Course syllabus for Analog electronics

Circuit analysis (EMI083, EMI084), Introductory course in mathematics (TMV156, TMV157) and Calculus in one variable (TMV136, TMV137) or equivalent.

The course shall give the student basic knowledge in analogue electronic circuits. The course is limited to circuits composed by operational amplifiers, resistors, capacitors, coils, transformers, diodes and transistors.

• Describe the major classes of electronic components and their basic functions and use.

• Analyze, design and verify fundamental amplifier circuits with discrete transistors with respect to the bias point and small signal parameters, and derive substantial small signal parameters of the circuit models and to analyze the small signal properties of some simple combinations of amplifier stages; analyze a differential amplifier with discrete transistors.

• Describe the ideal operational amplifier model and introduce basic non-idealities; explain the effect of negative feedback on the amplifier's properties; and use the model at an appropriate level of detail to analyze and design simple amplifier circuits, with calculation of rise time and pulse decay in the time domain ; and the link these properties to the Bode diagram in the frequency domain.

• Introduce some basic DC-related non-idealities in the operational amplifier model; describe how these non-idealities affect the operational amplifier behavior, and suggest compensating circuits for them.

• Describe the two major types of oscillators (harmonic and relaxation-based); analyze and design simple oscillators with respect to the oscillation frequency.

• Describe and discuss  simple transistor switches with inductive or capacitive load with respect to speed, currents, voltages and power; estimate power dissipation, inrush current and voltage overshoot and describe how the latter can be handled.

• Analyze and design simple rectifier and stabilizing circuits, in terms of power capacity, voltage fluctuations and power loss, using models of rectifier and zener diodes to support the analysis; explain the function of a synchronous rectifier.

• Analyze power output stages of class A and AB with respect to efficiency; and also describe the function of a class-D amplifier.

• Use data sheets, simulation tools and laboratory equipment to analyze and verify properties of the circuits studied in the course.
  

The course will give the student basic knowledge about analysis and synthesis of passive and active circuits consisting of resistors, capacitors, operational amplifiers, inductors, diodes and transistors.
Time and frequency properties are studied by use of established analysis methods and models.
Established computational methods and models are leading to plain and computationally simple results.
One focus of the course relates to operational amplifiers modeled as being ideal especially when associated with negative feedback with applications. The effects of negative feedback of more real operational amplifier models are discussed in detail.
Consequences of simplification from real to ideal operational amplifiers are discussed.
Another part of the course deals with the analysis of transistor circuits. This is carried out in two steps, static (DC) and dynamic (AC), where the dynamic behavior is analyzed by linearization around the operating point. The transistor mainly studied is the MOS transistor. A discrete implementation of an operational amplifier with MOS transistors is analyzed, simulated and evaluated in the laboratory work.
Bipolar Transistors are only briefly studied in the course.
Different types of oscillators are studied.
Transistor switches with inductive and capacitive load as well as rectifier and voltage stabilizing circuits with zener diodes are studied.
A short review of the power stages with bipolar transistors is given with respect to temperature and cooling problems.
Finally a short presentation of passive components, printed circuit boards and methods to connect components are given.

The course is given as  lectures and demonstration exercises in full class and exercises/ consultations in smaller groups. Hand-in problems should be solved individually and laboratory exercises shall be performed in a circuit lab.

Book:

If possible the latest edition of   Sedra & Smith, Microelectronic Circuits.

Copied material: Course-PM, Laboratory - PM, Passive components, Exercises.

The theoretical learning outcomes are examined by a half-time minor exam and a written final exam after the course. During the course optional hand-in problems will be done. Mandatory laborations including prepartory tasks will examine the more practical goals as well as analyzing skills. To receive the final grade both the written exam exam and the laboratory course must be passed.
