When designing a chip, a designer needs to consider many tradeoffs before developing the logic. For example, if a chip is being developed for mobile applications, power becomes a very important factor ...

Who would have thought that a circuit comprising only two 2-input NAND gates could be so complicated (or, should we say, “interesting”)? Up to this point (click here to see my earlier columns), the ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

In the context of analyzing digital semiconductor circuits, a glitch is any unwanted or unused signal transition, or toggle. A glitch is often a transient signal that is much shorter than a clock ...
