Computers, and other digital systems, are designed using elementary electronic circuits called gates. In this article, Inverters, Or gates, and And gates are introduced by logical statements justifying the term "logic design." Then, the...

Digital logic is a precise set of mathematical rules for representing the relationships and interactions of symbols stored in a digital computer. Binary logic, Boolean logic, and digital logic are often considered interchangeable terms, as nearly all...

by Terry Cleveland, Microchip Technology Many power circuits need digital control. those combining digital- and analog-circuit blocks provide the best of both worlds. Power ICs that combine analog and digital are becoming more common. Battery-charger applications have increased the need for...

System designers are advised against using pulldown resistors, as these can bring a host of problems to the user. Low resistor values also should not be shunned, even in CMOS circuits, since resistor value does not affect static pullups. Designers are also advised to...
