Digital electronics is a little more abstract than analog electronics, and trying to find a useful starter book can be tough. For those interested in learning digital electronics, with a practical approach, Beginning Digital Electronics Through Projects is for you. It is published in the same tradition as Beginning Analog Electronics Through Projects, Andrew Singmin's revision to the popular Beginning Electronics Through Projects.

Beginning Digital Electronics Through Projects provides practical exercises, building techniques, and ideas for over thirty-five useful digital projects. Some digital logic knowledge is necessary, but the theory is limited to "need-to-know" information that will allow you to get started right away without complex math. Many components in this text are common to either analog or digital electronics, and beginners or hobbyists making their start here will find and overview of commonly used components and their functions described in everyday terms.
Each of the projects builds on the theory and component knowledge developed in earlier chapters, establishing progressively more ambitious goals. Step-by-step learning instructions help you determine the best ways of working with such projects as Schmitt Trigger Circuits, Versatile ICs, Digital Support Circuits, and much more. Two interesting wireless projects (an FM receiver and an FM transmitter) bring the final chapters of this book to a close.

"Current Sources and Voltage References" provides fixed, well-regulated levels of current or voltage within a circuit. These are two of the most important "building blocks" of analog circuits, and are typically used in creating most analog IC designs.
Part 1 shows the reader how current sources are created, how they can be optimized, and how they can be utilized by the OEM circuit designer. The book serves as a "must-have" reference for the successful development of precision circuit applications. It shows practical examples using either BJTs, FETs, precision op amps, or even matched CMOS arrays being used to create highly accurate current source designs, ranging from nanoAmps to Amps. In each chapter the most important characteristics of the particular semiconductor type being studied are carefully reviewed. This not only serves as a helpful refresher for experienced engineers, but also as a good foundation for all EE student coursework, and includes device models and relevant equations.
Part 2 focuses on semiconductor voltage references, from their design to their various practical enhancements. It ranges from the simple Zener diode to today's most advanced topologies, including Analog Devices' XFET(R) and Intersil's FGA(TM) (invented while this book was being written). Over 300 applications and circuit diagrams are shown throughout this easy-to-read, practical reference book.
* Discusses how to design low-noise, precision current sources using matched transistor pairs.
* Explains the design of high power current sources with power MOSFETs
* Gives proven techniques to reduce drift and improve accuracy in voltage references.

FPGAs have almost entirely replaced the traditional Application Specific Standard Parts (ASSP) such as the 74xx logic chip families because of their superior size, versatility, and speed. For example, FPGAs provide over a million fold increase in gates compared to ASSP parts. The traditional approach for hands-on exercises has relied on ASSP parts, primarily because of their simplicity and ease of use for the novice. Not only is this approach technically outdated, but it also severely limits the complexity of the designs that can be implemented. By introducing the readers to FPGAs, they are being familiarized with current digital technology and the skills to implement complex, sophisticated designs. However, working with FGPAs comes at a cost of increased complexity, notably the mastering of an HDL language, such as Verilog. Therefore, this book accomplishes the following: first, it teaches basic digital design concepts and then applies them through exercises; second, it implements these digital designs by teaching the user the syntax of the Verilog language while implementing the exercises. Finally, it employs contemporary digital hardware, such as the FPGA, to build a simple calculator, a basic music player, a frequency and period counter and it ends with a microprocessor being embedded in the fabric of the FGPA to communicate with the PC. In the process, readers learn about digital mathematics and digital-to-analog converter concepts through pulse width modulation.
