Digital electronics: principles, devices, and applications / Anil Kumar Maini Digi. in the available books on the subject of digital Digital Electronics: Principles. I will highly recommend you to download the book Digital Electronics by Thomas -Floyd . It is very well written covering all different aspects needed for. Digital electronics is a very interesting subject, and here you will get a short description of top 6 books for digital electronics. these books are.

It also provides hands-on experience debugging real circuits, which students don't get when they use modern development boards for digital labs. So in terms of longevity, I scores this a 4 since this approach isn't really how students build digital circuits anymore. At the same time I appreciate the value of building some of these simple circuits to help build foundation knowledge before moving to the more complex topics.

It is apparent that this was the intent of the author also because the book does not go on for a thousand pages building every digital circuit ever imagined. It essentially gets to the beginning of a simple cpu and then stops. Clarity Very clear. The pictures are extremely valuable in making the content clear. Consistency rating: 5 Each new circuit is presented with the same methodical approach.

The functionality is presented followed by the synthesis of the logic diagram, then the circuit implementation is shown.

Another form of digital circuit is constructed from lookup tables, many sold as " programmable logic devices ", though other kinds of PLDs exist. Lookup tables can perform the same functions as machines based on logic gates, but can be easily reprogrammed without changing the wiring. This means that a designer can often repair design errors without changing the arrangement of wires. Therefore, in small volume products, programmable logic devices are often the preferred solution.

They are usually designed by engineers using electronic design automation software. Integrated circuits consist of multiple transistors on one silicon chip, and are the least expensive way to make large number of interconnected logic gates. Integrated circuits are usually interconnected on a printed circuit board which is a board which holds electrical components, and connects them together with copper traces. Design[ edit ] Engineers use many methods to minimize logic functions, in order to reduce the circuit's complexity.

When the complexity is less, the circuit also has fewer errors and less electronics, and is therefore less expensive. The most widely used simplification is a minimization algorithm like the Espresso heuristic logic minimizer [ needs update ] within a CAD system, although historically, binary decision diagrams , an automated Quine—McCluskey algorithm , truth tables , Karnaugh maps , and Boolean algebra have been used.

When the volumes are medium to large, and the logic can be slow, or involves complex algorithms or sequences, often a small microcontroller is programmed to make an embedded system. These are usually programmed by software engineers. When only one digital circuit is needed, and its design is totally customized, as for a factory production line controller, the conventional solution is a programmable logic controller , or PLC.

These are usually programmed by electricians, using ladder logic. Representation[ edit ] Representations are crucial to an engineer's design of digital circuits.

Some analysis methods only work with particular representations. The classical way to represent a digital circuit is with an equivalent set of logic gates. Each logic symbol is represented by a different shape. One of the easiest ways is to simply have a memory containing a truth table. The inputs are fed into the address of the memory, and the data outputs of the memory become the outputs.

For automated analysis, these representations have digital file formats that can be processed by computer programs. Most digital engineers are very careful to select computer programs "tools" with compatible file formats. Combinational vs. Sequential[ edit ] To choose representations, engineers consider types of digital systems.

Most digital systems divide into " combinational systems " and " sequential systems. It is basically a representation of a set of logic functions, as already discussed. A sequential system is a combinational system with some of the outputs fed back as inputs.

This makes the digital machine perform a "sequence" of operations. The simplest sequential system is probably a flip flop , a mechanism that represents a binary digit or " bit ". Sequential systems are often designed as state machines. In this way, engineers can design a system's gross behavior, and even test it in a simulation, without considering all the details of the logic functions.

Sequential systems divide into two further subcategories. Synchronous sequential systems are made of well-characterized asynchronous circuits such as flip-flops, that change only when the clock changes, and which have carefully designed timing margins.

Synchronous systems[ edit ] A 4-bit ring counter using D-type flip flops is an example of synchronous logic. Each device is connected to the clock signal, and update together. Main article: synchronous logic The usual way to implement a synchronous sequential state machine is to divide it into a piece of combinational logic and a set of flip flops called a "state register.

Digital Electronics: Principles, Devices and Applications

The fastest rate of the clock is set by the most time-consuming logic calculation in the combinational logic. The state register is just a representation of a binary number. If the states in the state machine are numbered easy to arrange , the logic function is some combinational logic that produces the number of the next state.

Asynchronous systems[ edit ] As of , most digital logic is synchronous because it is easier to create and verify a synchronous design. However, asynchronous logic is thought can be superior because its speed is not constrained by an arbitrary clock; instead, it runs at the maximum speed of its logic gates. Building an asynchronous system using faster parts makes the circuit faster. Nevertherless, most systems need circuits that allow external unsynchronized signals to enter synchronous logic circuits.

These are inherently asynchronous in their design and must be analyzed as such.

Examples of widely used asynchronous circuits include synchronizer flip-flops, switch debouncers and arbiters. Asynchronous logic components can be hard to design because all possible states, in all possible timings must be considered.
