The half adder now is: We can reduce the gate count considerably by introducing an XOR ... expression (X ⊕ Y) for both calculations in the logic diagram. Now we have the final full adder circuit ...

Let’s take a look at what it takes to create some fun, out-of-the-ordinary gate implementations. As an example, let’s consider the AND gate (the others are OR, NOT, NAND, NOR, XOR and XNOR).

A new technical paper titled “Non-Traditional Design of Dynamic Logics using FDSOI for Ultra-Efficient Computing” was published by researchers at University of Stuttgart, UC Berkeley, Indian Institute ...

Logic elements “Exclusive OR” are widely used in a variety of digital devices. However, in some cases, for example, when using increased operating voltages, the use of standard chips is impossible.

For those cases a simpler approach”such as the circuit in Figure 1″ will do the job just as well. Figure 1: This circuit doubles the input frequency. The reference frequency in this circuit drives the ...
