Free online course Electronic Circuit Design Course

About the free online course

Designing electronic circuits is more than connecting components: it is about predicting behavior, controlling gain and bandwidth, managing noise and non-idealities, and choosing architectures that meet real constraints. This free online course helps you move from theory to practical circuit design thinking, so you can analyze and size stages with confidence and explain why a circuit works, not just that it works.

You will develop a solid foundation in transistor-based amplifiers, including how emitter and common-emitter configurations behave, how current can be transformed into voltage, and how small-signal models make complex circuits manageable. You will also strengthen your intuition for biasing, operating regions, and the trade-offs between gain, impedance, and linearity—skills that are essential for technicians, electricians, and anyone working with embedded or mixed-signal hardware.

Operational amplifiers are treated as design tools rather than black boxes. You will learn the rules behind closed-loop behavior, understand the consequences of non-idealities such as offset voltage, and apply op-amps to create practical building blocks, from comparators and Schmitt triggers to active filters. Along the way, you will connect frequency-domain concepts such as Bode plots, resonance, and filter order to the outcomes you see on a bench or in a simulation, helping you make informed choices about stability and performance.

Power and conversion are also covered from a designer’s viewpoint: linear regulators, low-dropout concepts, and the efficiency advantages of switched-mode power supplies, including buck, boost, and inverting topologies. You will see how references, current sources, and mirrors support robust designs, and how supply specifications translate into system reliability.

To bridge analog and digital worlds, the course builds your understanding of ADC and DAC principles and the practical parameters that define real resolution and accuracy. You will also gain clarity on common hardware interfaces and the foundations of CMOS logic and multivibrators, providing a rounded skill set that supports troubleshooting, prototyping, and professional growth. If you are aiming to strengthen job-ready electronics competence, this course provides a coherent path from components to complete circuit behavior, with exercises that reinforce core decisions and calculations.
