In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

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 ...

Living cells make decisions based on information processing genetic programmes. Many of these programmes execute digital functions 1,2,3,4,5,6,7,8. The capability to build synthetic digital systems in ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...
