With the two diodes reversed and a 910 Ohm resistor removed, a NOR gate is created. The next step was to build a S-R latch using the NAND gates and inverters, which holds some basic memory.

On the path to exploring complex logic, let’s discuss the electrical properties that digital logic signals are comprised of. While there are many types of digital signals, here we are talking… ...

Consequently, nobody has been able to make reliable diodes, transistors or logic gates out of silicon nanowires. Today, Massimo Mongillo et amis at the Universite Joseph Fourier, Grenoble, in ...

The transistor turnson, and the logic-zero voltage at thecollector is approximately 0.6+V L +V CE,where V L is the low voltage and V CE is the collector-to-emitter voltage.When inputs A and B are at ...
