EEE2045 Study Notes

This is an extensive and meticulously detailed set of handwritten notes on electronics and circuit theory, covering a wide range of topics essential for students and enthusiasts. These notes offer a practical and easy-to-follow guide to fundamental concepts and advanced applications. The logical flow and step-by-step examples make complex topics simple to understand. Core Components & Basic Principles The collection begins with the building blocks of electronics, providing a solid foundation in semiconductors, diodes, and transistors. Diodes & Rectifiers: Learn about forward and reverse bias, dynamic resistance, and different diode models. The notes also provide a thorough breakdown of half-wave, full-wave, and bridge rectifiers, including calculations for Peak Inverse Voltage (PIV) and average DC voltage. Transistors (BJTs & FETs): Get a comprehensive understanding of Bipolar Junction Transistors (BJTs) and Field-Effect Transistors (FETs), including both JFETs and MOSFETs. The notes cover operating modes (cutoff, active, saturation), biasing techniques, and DC and AC analysis, with detailed examples for determining Q-points and applying Thevenin’s Theorem. Amplifiers & Frequency Response This section is dedicated to the critical topic of amplification, from single-stage to multi-stage circuits. Amplifier Configurations: Detailed analysis of Common Emitter, Common Collector, and Common Base amplifiers. The notes explain how to perform both DC and AC analysis, calculate voltage gain), input/output resistance, and power gain. Operational Amplifiers (Op-Amps): Explore the theory and practical applications of op-amps. The notes cover a variety of circuits, including the non-inverting op-amp, inverting op-amp, voltage follower, and summing amplifier. Core concepts like Common Mode Rejection Ratio (CMRR) and slew rate are clearly explained. Frequency Response: Understand how amplifiers behave at different frequencies. The notes explain the concepts of capacitive reactance, Miller's Theorem, and how to determine critical frequencies for low and high-frequency responses. Filters & Specialized Circuits The collection concludes with an in-depth look at various filter designs and other essential circuit types. Filters (Passive & Active): A dedicated section on both passive and active filters. You'll find detailed explanations and calculations for Low Pass, High Pass, and Band Pass filters. The notes also feature advanced designs like Sallen-Key filters and Multiple Feedback Band Pass filters, with formulas for cutoff frequency (fc), damping factor (DF), and quality factor (Q). Voltage Regulators & Limiters: Study Zener diodes and their use in voltage regulation, with a focus on their ideal and practical characteristics. The notes also cover limiter and clamping circuits, explaining how diodes can be used to modify signal thresholds.
