This article from the Programmable Logic Design Line website gives an in-depth tutorial on how to design an FPGA (field programmable gate array) from scratch. The article includes a design checklist and a step by step...

This animated gif illustrates the changing voltages a conventional inverting amplifier when it receives input from a current source rather than a voltage source. Notice that the input resistor does not offer any...

This lab, presented by the National Nanotechnology Infrastructure Network, introduces students to the temperature response of liquid crystals, and how they respond in different phases of matter. In addition to liquid,...

This interactive Java tutorial explores the many steps necessary to build a transistor on a silicon wafer. It allows you to explore how an individual Field Effect (FET) transistor is fabricated on a silicon wafer...

White paper prepared by Dr. Mike Cooke surveys the coming changes and looks at how III-V quantum dots offer the prospect of fast non-volatile computer memory devices.
