The XNOR gate is a digital logic gate that is the inverse of the XOR gate. It outputs a HIGH (1) signal only when both its inputs are LOW (0), and a LOW (0) signal otherwise.

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computatio… ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning &#82… ...

Figure 1 illustrates how YES, NOT, AND, OR, NAND, and NOR gates are implemented in RFL using a 2N7000 N-channel MOSFET and a 5V supply. (Note that the XOR and XNOR functions have been omitted here, ...

The most basic duty-cycle to analog-level conversion ... Figure 3: Make a frequency multiplier with a XOR gate, an op amp, two capacitors, an inductor, and a delay. The logic edges at the XOR output ...

NAND gates are significant because any Boolean function (AND, OR, NOT, XOR, XNOR), which play a basic role in the design of computer chips, can be implemented by using a combination of NAND gates.

Various logic gates—AND, OR, XOR, NAND, NOT, CNOT, and a half adder—could be put together using different combinations of robots. The DNA gates all take two inputs in the form of other molecules.

Using this approach, the researchers were able to make ultrafast (less than 100 fs operating time) all-optical XNOR, NOR, AND, XOR, OR and NAND logic gates, as well as a half-adder. And that’s not all ...
