Engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of ...

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 ...

One of the hardest things about studying electricity, and by extension electronics, is that you generally can’t touch or see anything directly, and if you can you’re generally having a pretty bad day.

The versatile phase-locked loop (PLL) allows multiplication of a reference frequency with an operating frequency that ranges from “DC to daylight.” A PLL is overkill for some applications, however, ...

Toshiba Electronics has expanded its TC74VHC family of high-speed logic with a range of devices that combine Schmitt trigger inputs with voltage-tolerant output capabilities. The logic ICs can operate ...

Multiple droplets of a magnetic fluid have been used to create all of the fundamental logic circuits within a computer. Created by researchers in the US, the circuits are made by having the ...

Before we plunge headfirst into the fray with gusto and abandon (and aplomb, of course), let’s remind and reassure ourselves that—although the following discussions focus on the devices and ...
