At what age did you begin learning about electronics? What was the state of the art available to you at the time and what kinds of things were you building? For each reader these answers can be wildly ...

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

Foundries and packaging houses are wrestling how to control heat in the testing phase, particularly as devices continue to shrink and as thermally sensitive analog circuits are added into SoCs and ...

EVANSTON, Ill. — Transistors based on a new kind of material created by Northwestern University researchers have been lifted into outer space on the space shuttle Endeavour and attached to the outside ...
