Only eight lithography masks to create a low-power custom logic chips, compared with 20+ for CMOS, is the claim of Nottingham-based fabless chip start-up ‘Search For The Next’ (SFN). As such, ...

Logical microcircuits in transistor cans are now being offered by four major companies: Fairchild Semiconductor Corp., Raytheon Co., Philco Corp., General Instrument ...

The circuitry we rely on today comes from what could be considered a top-down approach, with the wiring completely laid out before it's etched into silicon. With the advent of nanotechnology, however, ...

Invigorating the idea of computers based on fluids instead of silicon, researchers have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ...

One of the favorite pastimes of electronics hobbyists is clock making. Clocks are a simple enough concept with a well-defined goal, but it’s the implementation that matters. If you want to build a ...

This Design Idea describes a new class of logic gates, which we have named resistor-FET-logic, aka “RFL.” How do we know it is new? While FET switches are common today, we have been unable to find a ...

As we have observed in previous parts of this course, in a digital system, signals can take on only two values: high or low. These values are often represented by two voltage levels. The most used ...

A few months ago, a tweet by [Ken Shirriff] asking about simple digital simulators caught my attention. The topic came up again in May when a repair video by [CuriousMarc] featured one such simulator ...

University of Houston have created an elastic semiconductor with 8.57cm2/Vs charge carrier mobility, and then made transistors, logic and a sensor array from it. Carrier mobility is largely retained ...
