(PhysOrg.com) -- Most of today’s electronics devices contain two different types of field-effect transistors (FETs): n-type (which use electrons as the charge carrier) and p-type (which use holes).

Researchers at Manchester University in the UK have used graphene to make a new electrically-controlled switching device that supports both memory and logic functions. The device, which exploits ...

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 ...

It’s possible to use an 8:1 multiplexer to implement any 3-input logical function, but can we use it to implement a 4-input function? On the one hand, some logic problems never seem to go away. On the ...

How can cells be programmed to respond to complex signals and make targeted decisions, similar to a logical circuit in a computer? An interdisciplinary team from two research groups at the Centre for ...
