1. Instead of the conventional method using the general/particular solutions to solve differential equations for the circuits containing inductors/capacitors, this book lays emphasis on the Laplace transform method for solving differential equations. We recommend taking the Laplace transform of electric circuits (containing inductors/capacitors) and setting up the transformed circuit equations directly in the unified framework (as if they were just made of resistors and sources) rather than setting up the circuit equations in the form of differential equations and then taking their Laplace transforms to solve them. The Laplace transform and the inverse Laplace transform are introduced in the Appendix. 2. This book presents several MATLAB programs that can be used to get the Laplace transformed solutions, take their inverse Laplace transforms, and plot the solutions along the time or frequency axis. The MATLAB programs can save a lot of time and effort for obtaining the solutions in the time domain or frequency domain so that readers can concentrate on establishing circuit equations, gaining insights to the problems, and making observations/interpretations of the solutions. 3. This book also introduces step by step how to use OrCAD/PSpice for circuit simulations. For circuit problems taking much time to solve by hand, the readers are recommended to use MATLAB and PSpice. This approach gives the readers not only information about the state of the art, but also self-confidence on the condition that the graphical solutions obtained by using the two software tools agree with each other. The OrCAD/PSpice is introduced in the Appendix. However, the portion of MATLAB and PSpice is kept not large lest the readers should be addicted to just using the software and tempted to neglect the importance of the basic circuit theory. 4. We make each example show something different from other examples so that readers can efficiently acquire the essential circuit analysis techniques and gain insights into the various types of circuits. On the other hand, instead of repeating similar exercise problems, we make most exercise problems arouse readers’ interest in practical application or help form a view for circuit application and design. 5. For representative examples, the analytical solutions are presented together with the results of MATLAB analysis (close to the theory) and PSpice simulation (close to the experiment) in the form of trinity. We are sure that this style of presentation will interest many students, attracting their attention to the topics on circuits efficiently. 6. Unlike most circuit books with a similar title, our book deals with positive-feedback op-amp circuits as well as negative-feedback op-amp circuits.

Provides practical examples of circuit design and analysis using PSpice, MATLAB, and the Smith Chart This book presents the three technologies used to deal with electronic circuits: MATLAB, PSpice, and Smith chart. It gives students, researchers, and practicing engineers the necessary design and modelling tools for validating electronic design concepts involving bipolar junction transistors (BJTs), field-effect transistors (FET), OP Amp circuits, and analog filters. Electronic Circuits with MATLAB®, PSpice®, and Smith Chart presents analytical solutions with the results of MATLAB analysis and PSpice simulation. This gives the reader information about the state of the art and confidence in the legitimacy of the solution, as long as the solutions obtained by using the two software tools agree with each other. For representative examples of impedance matching and filter design, the solution using MATLAB and Smith chart (Smith V4.1) are presented for comparison and crosscheck. This approach is expected to give the reader confidence in, and a deeper understanding of, the solution. In addition, this text: Increases the reader's understanding of the underlying processes and related equations for the design and analysis of circuits Provides a stepping stone to RF (radio frequency) circuit design by demonstrating how MATLAB can be used for the design and implementation of microstrip filters Features two chapters dedicated to the application of Smith charts and two-port network theory Electronic Circuits with MATLAB®, PSpice®, and Smith Chart will be of great benefit to practicing engineers and graduate students interested in circuit theory and RF circuits.

Used collectively, PSPICE and MATLAB are unsurpassed for circuit modeling and data analysis. PSPICE can perform DC, AC, transient, Fourier, temperature, and Monte Carlo analysis of electronic circuits with device models and subsystem subcircuits. MATLAB can then carry out calculations of device parameters, curve fitting, numerical integration, nume

Software tools applied to circuit analysis and design are rapidly evolving, enabling students to move beyond the time-consuming, math-intensive methods of traditional circuit instruction. By incorporating MATLAB 7.0 and PSpice 10.0, alongside systematic use of the Laplace transform, Yang and Lee help readers rapidly gain an intuitive understanding of circuit concepts. Unified scheme using the Laplace transform accelerates comprehension Focuses on interpreting solutions and evaluating design results, not laborious computation Most examples illustrated with MATLAB analyses and PSpice simulations Downloadable programs available for hands-on practice Over 130 problems to reinforce and extend conceptual understanding Includes expanded coverage of key areas such as: Positive feedback OP Amp circuits Nonlinear resistor circuit analysis Real world 555 timer circuit examples Power factor correction programs Three-phase AC power system analysis Two-port parameter conversion Based on decades of teaching electrical engineering students, Yang and Lee have written this text for a full course in circuit theory or circuit analysis. Researchers and engineers without extensive electrical engineering backgrounds will also find this book a helpful introduction to circuit systems.
