Basic Logic Gates Using NAND Gate

This is very simple and useful project which gives an idea about how to build the simple logic gates i.e. AND, OR & NOT gates using one of the universal gates – NAND Gate. This is very simple and ...

Efficient logic optimization utilizing complementary behavior of CMOS gates

Any typical digital design style with CMOS uses complementary pairs of p-type and n-type MOSFETs for logic functions implementation. Naturally, CMOS always ought to provide INVERTED outputs like ...

Low Power Universal Gates for Approximate Computing

Density and speed of IC’s have increased exponentially for several decades, following a trend described by Moore’s Law. While it is accepted that this exponential improvement trend will end, it is ...

Light Emitting Logic Gates Built From Scratch

What’s the weirdest computer you can think of? This one’s weirder. [Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor).

From Gates To FPGA’s – Part 1: Basic Logic

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning — but even ...

From light to logic: First complete logic gate achieved in soft material using light alone

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of ...

How to Read Datasheets: Logic ICs (Part 5)

In this column, we consider the evolution of complementary metal-oxide semiconductor (CMOS) technology, which was invented by Frank Wanlass in 1963. In this column, we consider the evolution of ...
