A chip scale atomic clock (CSAC) is a compact, low-power atomic clock fabricated using techniques of microelectromechanical systems (MEMS) and incorporating a low-power semiconductor laser as the light source.
Kitching's research focuses on the development of compact devices and instruments that combine elements of precision atomic spectroscopy, silicon micromachining and photonics. In the early 2000s, he and his group pioneered the development of chip-scale atomic clocks and magnetometers based on a patent [5] filed with the USPTO in 2001. These ...
Atomic clocks on the scale of one chip require less than 30 milliwatts of power. [35] [36] The National Institute of Standards and Technology created a program NIST on a chip to develop compact ways of measuring time with a device just a few millimeters across. [37]
In 1999, he went on to work at Agilent Technologies, a spin-off from H-P, where he developed quartz oscillators, atomic clocks, and used the Global Positioning System to synchronize clocks worldwide. [3] Towards the end of his time there, he concentrated on designs related to the chip scale atomic clock.
Elizabeth Ann Donley (born April 5, 1970) is an American physicist. She is a researcher in the time and frequency division at the Physical Measurement Laboratory.Donley's research areas include the operation and development of atomic fountain clocks and chip scale atomic devices and instruments.
Hitachi's 16 Mb SRAM memory chip in 1993. [47] Hitachi and NEC introduced 256 Mb DRAM memory chips manufactured with this process in 1993, followed by Matsushita, Mitsubishi Electric and Oki in 1994. [47] NEC's 1 Gb DRAM memory chip in 1995. [47] Hitachi's 128 Mb NAND flash memory chip in 1996. [47]
Nvidia dominates the AI chip market with an estimated 80% to 95% share in AI accelerators, according to multiple analysts. The company's H100 Graphics Processing Unit (GPU), which sells for up to ...
