This is a Electronic Devices and Circuits laboratory Manual, meant for II year Electronics, Electrical engineering students. All the circuits in this book ar tested.

This lab manual accompanies Electronic Devices and Circuits, 4/e.

This book is evolved from the experience of the author who taught all lab courses in his three decades of teaching in various universities in India. The objective of this lab manual is to provide information to undergraduate students to practice experiments in electronics laboratories. This book covers 118 experiments for linear/analog integrated circuits lab, communication engineering lab, power electronics lab, microwave lab and optical communication lab. The experiments described in this book enable the students to learn: • Various analog integrated circuits and their functions • Analog and digital communication techniques • Power electronics circuits and their functions • Microwave equipment and components • Optical communication devices This book is intended for the B.Tech students of Electronics and Communication Engineering, Electrical and Electronics Engineering, Biomedical Electronics, Instrumentation and Control, Computer Science, and Applied Electronics. It is designed not only for engineering students, but can also be used by BSc/MSc (Physics) and Diploma students. KEY FEATURES • Contains aim, components and equipment required, theory, circuit diagram, pin-outs of active devices, design, tables, graphs, alternate circuits, and troubleshooting techniques for each experiment • Includes viva voce and examination questions with their answers • Provides exposure on various devices TARGET AUDIENCE • B.Tech (Electronics and Communication Engineering, Electrical and Electronics Engineering, Biomedical Electronics, Instrumentation and Control, Computer Science, and Applied Electronics) • BSc/MSc (Physics) • Diploma (Engineering)

The laboratory investigations in this manual are designed to demonstrate the theoretical principles set out in the book Fundamentals of Electronic Devices and Circuits, 5/e. A total of 43 laboratory investigations are offered, involving the construction and testing of the circuits discussed in the textbook. Each investigation can normally be completed within a two-hour period. The procedures contain some references to the textbook; however, all necessary circuit and connection diagrams are provided in the manual so that investigations can also be preformed without the textbook.

The emphasis is first on understanding the characteristics of basic circuits including resistors, capacitors, diodes, and bipolar and field effect transistors. The readers then use this understanding to construct more complex circuits such as power supplies, differential amplifiers, tuned circuit amplifiers, a transistor curve tracer, and a digital voltmeter. In addition, readers are exposed to special topics of current interest, such as the propagation and detection of signals through fiber optics, the use of Van der Pauw patterns for precise linewidth measurements, and high gain amplifiers based on active loads.
