As I mentioned in my recent columns on the topic of adding pull-up or pull-down resistors to the inputs of unused or partially used logic gates and functions (see Part 1, Part 2, and Part 3), I was ...

A flip-flop is one of the most basic digital electronic circuits. It can most easily be built from just two transistors, although they can and have been built out of vacuum tubes, NAND and NOR gate… ...

Project 54/74 Maps Out Logic ICs. 4 Comments . by: Lewin Day. April 4, 2017. Title: Copy. Short Link: Copy. Integrated circuits are a fundamental part of almost all modern electronics, ...

The Multitester-project. The Multitester circuit consists of three ICs and a small loudspeaker. Its simplicity however does not prevent it from being able to check for four different parameters at any ...

Logic testers are simple but very helpful devices in testing digital circuits. A logic probe can be designed in many different ways. In this particular design, a combination of discrete and TTL logic ...

The logic circuit, ... of Engineering & Applied Science at Washington University in St. Louis is the lead author of an article describing the project in the Oct. 7 issue of Nature.

Spintronic computing promises superior energy efficiency and nonvolatility compared to conventional field-effect transistor logic. But, it has proven difficult to realize spintronic circuits with ...
