Prior to integrated circuits, these electronic components were discrete devices soldered to each other on a printed circuit board. To learn how a digital circuit works, go to half adder and travel ...

Printed large-scale integrated circuits, LSI, can be used, for example, to power an electrochromic display, itself manufactured as printed electronics. (Image: Thor Balkhed, Linköping University) The ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

Interestingly, the first integrated circuits came in the vacuum technology! A radio receiver was taxed based on the number of ...
