Circuits can also be designed for any type of Boolean logic function, such as AND gates and OR gates. Using those kinds of gates, circuits can detect multiple inputs. In most of the previously ...
Discrete small-signal MOSFETs still find uses today, and this Design Idea presents two simple examples: an AND gate, and an amplitude modulator. Figure 1 shows a standard two-input AND gate along with ...
Biocomputing—it’s not just for Star Trek Borgs anymore! Scientists at Johns Hopkins have engineered cells that behave like AND and OR Boolean logic gates, taking an important step toward using living ...
