Electronic Circuits 2

Course summary

In this course, you will learn about the functioning, analysis and design of important electronic circuits, such as (multi-stage) amplifiers, signal generators, sine-wave oscillators, CMOS logic gates, memory circuits and data converters. Furthermore, you will develop practical skills in the application and utilization of the acquired theoretical knowledge by solving various numerical problems and exercises. In the Lab practicum, you will be able to become familiar with some of these electronic circuits by building and measuring your own sine wave oscillator.

Learning objectives

By completion of the course, the students should be able to:

  • demonstrate knowledge and understanding of basic electronic circuits, in particular of (multi-stage) amplifiers, signal generators, oscillators, CMOS logic gates, memory circuits and data converters;
  • ​apply the acquired knowledge in solving problems and building real-life practical circuits, in particular of sine wave oscillators.
  • demonstrate knowledge and understanding of basic electronic circuits, in particular of (multi-stage) amplifiers, signal generators, oscillators, CMOS logic gates, memory circuits and data converters;
  • ​apply the acquired knowledge in solving problems and building real-life practical circuits, in particular of sine wave oscillators.

The specific skills that the students will be capable upon completion of the course include:

  • Functionally translate NMOS based circuits into PMOS equivalents;
  • Estimation of the time constants in an electronic circuit;
  • Applying the Barkhausen criteria for oscillations;
  • Analyzing and guaranteeing the amplifier stability;
  • Designing, modeling, simulating, implementing and measuring of a 10kHz oscillator;
  • Sizing of digital gates and memories;
  • Analyzing the basic properties of D/A and A/D converters.

Feedback

"On behalf of the students we would like to compliment you for the way you explained the pre-knowledge of Control Systems concerning Transfer functions, Poles/Zeros, S-Plane today. Connecting the dots from a simple circuit to a transfer function to explaining the S-plane was really helpful!"

"You showed the full path from the practical circuit level to the rather abstract S-plane level in a really clear way. Thank you for all the energy you put into this, from a student’s point of view, rather difficult course!"
