The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the ...

The circuit is not designed to be used in a computer chip. Instead, it is a proof of principle that allowed the research team to test the switching speed of its design. "The ring oscillator is a very ...

The manufacture of IC chips used in computers is made up of the complex interactions of various companies around the world. A site that illustrates the state of the international supply chain of ...
