Building logic gates out of silicon is old hat, as is building them from discrete transistors, 555 chips, LEGO, and even gears. [Yukio-Pegio Gunji] and [Yuta Nishiyama] from Kobe University, along ...

A research team from Siemens in Germany and the University of Bielefeld has developed the magnetic techniques needed for a new generation of low-power reconfigurable logic. The team has used 'spin ...

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computations ...

(Nanowerk Spotlight) Logic gates, especially Boolean logic gates, are the fundamental building blocks of today's computers built with silicon-based circuitry; without them, digital information could ...

You can assemble a pulse-generation circuit from a simple Schmitt-input AND gate plus a resistor-capacitor timing network. However, if you need a logic function that's not a standard catalog item, you ...

You can use the circuit described in this DesignIdea to estimate voltages across 10- to 100-MΩresistances. It also works for reverse-biased diodes. The common CMOS gates in Figure 1 have aninput ...

The ability for cells to control gene expression in response to changing conditions is crucial for their survival. People spend their entire careers teasing apart these mechanisms, many of which are ...
