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 ...

The digital world offers many advantages over its analog relatives, the use of boolean logic among them. Some of the functions, like NOT, OR, and AND are fairly straightforward and line up nicely with ...

A technical paper titled “The RGATE: an 8-in-1 Polymorphic Logic Gate Built from Reconfigurable Field Effect Transistors” was published by researchers at TU Dresden and NaMLab. “We present the ...

I fear the topic of this column is poised to unleash a tsunami of controversy. My engineering accomplice Joe Farr says that this is one of those topics that, when presented to 10 different engineers, ...

Multiplying two analog signals involves the use of analog multipliers, usually implemented by using log and antilog circuit blocks or the Gilbert cell. Today, the most common technique used to ...

Oscillators, also called astable multivibrators, are electronic devices that generate a periodic signal. They are employed in a large number of applications such as clocks, oscillophones, musical ...

Hydrogel NAND gate; long-distance remote epitaxy; PAM-8 receiver.

Forward-looking: Semiconductors are essential for today's electronics, providing computational capabilities and the ability to control electric signals. They are also highly complex and costly, so ...
