Chapter 1 introduces the foundational passive circuit elements: resistors, capacitors, inductors, and the memristor. Kirchhoff’s laws are mentioned. Key concepts, including current, voltage, and power dissipation, are discussed in the context of circuits involving these elements. Both independent and dependent current and voltage sources are discussed and illustrated with practical examples. The chapter provides a detailed exploration of source transformations, supported by several examples, and introduces Thevenin’s and Norton’s theorems. Additionally, ideal amplifier concepts are presented to establish a basis for further study. Chapter 2 delves into the crystal structures and electronic properties of various materials, including conductors, semiconductors, and insulators. A detailed exploration of intrinsic and doped semiconductors (p-type and n-type) is provided. Drift and diffusion currents in semiconductors are illustrated through practical examples, and the p-n junction is analyzed comprehensively, emphasizing its role in electronic devices. Chapter 3 thoroughly discusses ideal and physical diodes, as well as other diode models. Various diode circuits are analyzed, focusing on vin–vout and time-domain characteristics. The content is enriched with numerous examples and supported by extensive SPICE simulations to enhance comprehension. Chapter 4 explores DC analysis of npn and pnp BJTs, focusing on their operation across four distinct regions. Special attention is given to circuits operating in the forward-active region that is crucial for amplifier applications. As a practical example, the power dissipation of a BJT circuit is analyzed. A SPICE simulation is provided to illustrate key concepts. Chapter 5 explores metal-oxide-semiconductor field-effect transistors (MOSFETs), focusing on DC analysis of MOSFET-based circuits across three key operating regions: saturation, resistive (triode), and cut-off. Special emphasis is placed on circuits operating in the saturation region which are practicularly important for amplifier design. A SPICE simulation is provided to support the analysis. Chapter 6 focuses on the small-signal analysis of BJT-based amplifiers. It examines key amplifier topologies, including the common-emitter, common-base, and common-collector (emitter follower) configurations. SPICE simulations are included to illustrate the behavior and performance of these circuits. Chapter 7 focuses on the small-signal analysis of MOSFET-based amplifiers, including common-source, common-gate, and common-drain (source follower) configurations. Practical insights into the behavior of these amplifiers are supported through several SPICE simulations
