Did you know that most AVR chips have a type of hardware exclusive OR (XOR) option when it comes to the logic levels of the output pins? If you look in the datasheet (the image above is a ...

In addition to NAND gates, the development of all-optical XOR logic gates has also been explored. Similar to the NAND gate, the XOR gate was designed using a PC-SOA and Mach-Zehnder interferometer ...
