Four-phase logic
Four-phase logic is a type of, and design methodology for, dynamic logic; it enabled non-specialist engineers to design quite complex ICs, using either PMOS or NMOS processes.-History:R. K...

Logic gate
A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logic inputs and produces a single logic output. Depending on the context, the term may refer to an ideal logic gate, one that has for instance zero rise time and...
