The heart of NIST's next-generation miniature atomic clock -- ticking at high "optical" frequencies-- is this vapor cell on a chip, shown next to a coffee bean for scale. Conventional vapor cell atomic clocks are about the size of a deck of cards, consume about 10 W of electrical power and cost about $3,000.
Sony's 16 Mb SRAM memory chip in 1994. [47] NEC VR4300 (1995), used in the Nintendo 64 game console. Intel Pentium Pro (1995), Pentium (P54CS, 1995), and initial Pentium II CPUs (Klamath, 1997). AMD K5 (1996) and original AMD K6 (Model 6, 1997) CPUs. Parallax Propeller, 8 core microcontroller. [100]
Reducing the size and power consumption of optical clocks is necessary to enable their use in geodesy and GPS navigation. In August 2004, NIST scientists demonstrated a chip-scale atomic clock that was 100 times smaller than an ordinary atomic clock and had a much smaller power consumption of 125 mW.
Wafer-level chip-scale package: A WL-CSP or WLCSP package is just a bare die with a redistribution layer (or I/O pitch) to rearrange the pins or contacts on the die so that they can be big enough and have sufficient spacing so that they can be handled just like a BGA package.

The atomic scale thickness of graphene provides a pathway for accelerometers to be scaled down from micro to nanoscale while retaining the system's required sensitivity levels. [ 35 ] By suspending a silicon proof mass on a double-layer graphene ribbon, a nanoscale spring-mass and piezoresistive transducer can be made with the capability of ...
Products included hydrogen masers, rubidium and cesium atomic standards, temperature and oven controlled crystal oscillators, miniature and chip scale atomic clocks, network time servers, network sync management systems, cable timekeeping solutions, telecom synchronization supply units (SSUs), and timing test sets.
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter.
Semiconductor device modeling creates models for the behavior of semiconductor devices based on fundamental physics, such as the doping profiles of the devices. It may also include the creation of compact models (such as the well known SPICE transistor models), which try to capture the electrical behavior of such devices but do not generally ...
