About this course

Transistors are the fundamental building blocks of modern electronics, powering everything from simple amplifiers to complex microprocessors. Understanding how these semiconductor devices operate is essential for anyone looking to design, analyze, or troubleshoot electronic circuits. This written course guides you through the foundational physics, operational modes, and practical applications of the two most important transistor families: Bipolar Junction Transistors (BJTs) and Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs). You will transition from learning basic semiconductor concepts to analyzing switching and amplification circuits through clear explanations and structured written exercises. What you'll learn: - Understand the physical structure and key differences between BJTs and MOSFETs - Analyze transistor operating regions, including cutoff, active, saturation, and triode modes - Calculate current amplification, bias points, and switching behavior in practical circuits - Design basic amplifier and electronic switch configurations using step-by-step mathematical models - Explore modern semiconductor trends, including low-power design principles and the transition to FinFET architectures The course begins with essential semiconductor physics and terminology before diving deep into the DC and AC characteristics of both BJTs and MOSFETs. You will progress through detailed circuit analysis techniques and practical design scenarios, solidifying your knowledge with written practice problems. This course is designed for beginners, electronics enthusiasts, and students seeking a solid foundation in semiconductor devices, requiring only basic algebra and introductory circuit knowledge. Start reading today to unlock the core principles of modern electronic design.
