In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to encapsulate circuits in compact integrated circuits to hold hundreds or thousands of logic circuits. This article discusses the most important ones, with some practical uses. Introduction … Read more
In the first installment of this course, we learned that a digital value is a quantity that varies “in steps” and can take on only a finite number of values. In today’s logic systems, only two possible signal states are handled: true logic (1) and false logic (0), which are translated into appropriate electrical voltages. … Read more
The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this article, however, other logic gates are examined. By appropriately combining multiple logic gates, it is possible to build compound logic systems with even more important … Read more
The previous article discussed the concept of logic propositions and how they can be used to create fundamental electronic circuits. In this article, another important aspect of digital electronics will be explored, namely that involving logic gates. The different types of logic gates available and how they work will be discussed. This will be an … Read more
Two years ago in New York’s Union Square, the bright letters of a new climate clock counted down the critical time window remaining for humanity to act and save the planet from a climate catastrophe. To remain under the crucial 1.5˚C warming and prevent the worst effects of climate change from becoming irreversible, we were warned we … Read more
As seen in earlier articles, the only two possible states of information for digital electronics are true and false. Be it an electric current, a numeric datum, or a variable of any kind, the system’s final choices depend solely on the value of these facts. Binary electronics, in fact, has this name for this reason. … Read more
Numbering systems are sets of symbols used to represent numbers and values. It has methods and rules for counting and performing many mathematical operations. In Part 3 of our Digital Electronics Course, we will delve into this very concept, as it underlies all methodologies applied to digital electronics. Positional numbering systems Performing arithmetic and mathematical … Read more
TSMC has certified the Cadence digital and custom/analog design flows for its N4P and N3E process technologies. These design flows support TSMC’s latest Design Rule Manual (DRM) and FINFLEX technology. Through continued collaborations, the two companies have delivered the corresponding N4P and N3E process design kits (PDKs) to accelerate advanced-node mobile, automotive, AI, and hyperscale … Read more
In Part 2 of our Digital Electronics Course, we will get a better understanding of the importance of digital electronics compared to analog electronics. Systems are made much simpler at both the software and hardware levels when you can choose between two different voltage levels without having to worry about controlling the actual potential difference … Read more
Today, we are surrounded by digital electronics. Devices that work with analog electronics are very rare. Computers, telephones, cameras, CD players, printers, radios, and TVs all operate with digital technology. We hear about digital electronics every day, but few people probably really know its meaning and function. There are several definitions to describe it. Digital … Read more
