DARPA circuit achieves speed of 1 terahertz (THz)

Guinness World Records has officially recognised DARPA's Terahertz Electronics program for creating the fastest solid-state amplifier integrated circuit ever measured. The ten-stage common-source amplifier operates at a speed of one terahertz (1,000,000,000,000 Hz), or one trillion cycles per second — 150 billion cycles faster than the existing world record of 850 gigahertz set in 2012.
