A couple years back we covered a very impressive transistor logic clock which was laid out so an observer could watch all of the counters doing their thing, complete with gratuitous blinkenlights. It ...

On the path to exploring complex logic, let’s discuss the electrical properties that digital logic signals are comprised of. While there are many types of digital signals, here we are talking about ...

Logic signals have fallen from the 15V of the old CMOS 4000 series to 5V TTL (transistor-to-transistor logic) to modern CMOS levels of 3.3, 2.7, and 1.8V. Advanced processes use digital logic that ...

A variety of logic-circuit techniques have been in use since the 1960s, when integrated logic first came into existence. In the beginning was Resistor-Transistor Logic (RTL). Then came ...

New technical paper titled “Multi-functional multi-gate one-transistor process-in-memory electronics with foundry processing and footprint reduction” from researchers at Ningbo Institute of Materials ...

The transistor, an invention that heralded a new era in electronics, is the key component of practically all integrated circuits (ICs) and microprocessors. The point-contact transistor that Walter H.

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the first ...

This is the third installment in our CPU design series. In Part 1, we covered computer architecture and how a processor works at a high level. Part 2 explored the design and implementation of ...
