TAILIEUCHUNG - The Devices

A diode is a semiconductor device which allows current to flow through it in only one direction. Although a transistor is also a semiconductor device, it does not operate the way a diode does. A diode is specifically made to allow current to flow through it in only one direction. | Digital Integrated Circuits A Design Perspective The Devices Jan M.
