QSPICE is an analog and mixed-signal simulator characterized by high simulation speed, accuracy and reliability. It is a new program and can be downloaded here. QSPICE is still in the demonstration ...

In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

Chaotic circuits can arise from either computed (using Analog Computers or Digital Computers) solutions to coupled differential equations or from unstable systems/circuits. A new open-source circuit ...

Hardware hacking often seems like black magic to the uninitiated, which is why 123D Circuits is so cool: it allows you to learn electronics using a virtual Arduino board and breadboard without blowing ...

The first CMOS chip was created by Fairchild Semiconductor, presented at ISSCC in 1963. The logic topologies used in today’s textbooks originated in this work. P-type devices are slower than N-type by ...

One of the dreams of makers the world over is to be able to print electronic circuits on more or less any surface using a desktop printer. The great promise is the possibility of having RFID circuits ...

After several years of experimentation, and growing success in volume manufacturing for some use cases, technologies for 3D printing of electronic circuits are becoming more common. Some innovations ...

(Nanowerk Spotlight) Circuit boards form the foundation of modern electronics, but their production relies on materials that persist in the environment for centuries. These boards must meet precise ...
