A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.220010 considers optical logic gates in future computers. If you are reading this on your smartphone, its CPU (central processing ...

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 ...

Researchers have devised a way to make computer vision systems more efficient by building networks out of computer chips’ logic gates. Networks programmed directly into computer chip hardware can ...

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 ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...

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 ...
