The classic Schmitt-trigger-based RC oscillator is "hacked" and analyzed using the simulation software QSPICE.

ABSTRACT: A new nano-based architectural design of multiple-stream convolutional homeomorphic error-control coding will be conducted, and a corresponding hierarchical implementation of important class ...

We may receive a commission on purchases made from links. To co-opt a term from the marketing industry, the most "toyetic" vehicle employed by the United States military, and indeed most world ...

3:53 p.m. July 7, 2025: An earlier version of this article said that Ryan Cavalieri’s car was nitrogen gas-powered. The car is powered by nitromethane, a nitrogen compound, and methanol. The neon ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

A simple RC circuit can’t function as an inverter, but a previous tutorial explored how an RC circuit’s output behaves when driven by an exponentially damped RLC circuit, offering insightful ...

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 ...

A variety of linear models are available to represent common active electronic devices such as transistors and vacuum tubes. Devices operating under large-signal conditions often require nonlinear ...
