Sometimes it involves technological breakthroughs with huge potential. Guinness has handed DARPA’s Terahertz Electronics program the award for the fastest solid-state amplifier integrated circuit. Developed by Northrop Grumman, the Terahertz Monolithic Integrated Circuit (TMIC) is a ten-stage common-source amplifier that cranks speeds of one terahertz (1012 Hz), or one trillion cycles per second.
