Basics of Analog Electronics: BJTs, MOSFETs, and Diode Circuits

Understanding how electronic components manipulate signals is the foundation of hardware engineering and circuit design. This written course guides you through the core concepts of analog electronics, starting with essential semiconductor physics and foundational terminology before moving on to practical components. You will learn how to analyze, design, and troubleshoot circuits that form the backbone of modern hardware systems. What you will learn: Understand the physical principles of semiconductor materials and diode behavior; Analyze and configure clipper and clamper circuits to shape analog waveforms; Master the operations and bias configurations of Bipolar Junction Transistors (BJTs); Explore the mechanics of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) as switches and amplifiers; Practice analyzing circuit diagrams and predicting voltage and current outputs; Learn modern simulation-ready design principles to verify your calculations. This course begins with the absolute basics of charge carriers and PN junctions, progressing systematically through diodes, transistors, and signal-shaping circuits. It is designed specifically for beginners, engineering students, and hobbyists with no prior background in electronics. Start building your foundational knowledge of analog hardware design today.
