The order of precedence is less well defined for logic circuits, like XOR or NAND, which are derived from the three basic circuits. It is best to use parenthesis to clarify the order of operations ...

Logical functions. When studying logic, one must begin with the basic functions. Input values can be combined using the logical AND, OR, and exclusive OR (XOR) functions (Fig. 1 at right). Logic gates ...

FDSOI FET allows the threshold voltage ( V t ) to be adjustable (i.e., low-Vt and high-Vt states) by using the back gate bias. Our design utilizes the front and back gates of an FDSOI FET as the input ...

As designers, we're used to representing digital functions using Boolean expressions in conventional sum-of-products or product-of-sums forms, which we predominantly implement using AND, OR, NAND, NOR ...

The optoelectronic logic element AND, OR and XOR is considered, the output signal of which can be inverted when the input control signal is applied, thereby converting the logic element into NAND, NOR ...
