A series of MOS monolithic integrated circuits (MOSMICs) that will allow designers to upgrade the performance of UHF and VHF tuners at no additional cost has been announced by Vishay Intertechnology. Serving as a low-noise RF input stage, the 'X' devices provide improved automatic gain control and cross modulation behaviour compared with previous-generation MOSMICs.
Magnetic materials, built up as multi-layered sandwiches with successive layers only a few atoms thick, are giving computers larger memories. By building up sandwiches of magnetic and non-magnetic materials one layer of atoms at a time, it is possible to manipulate, enhance and control the magnetic properties of such sandwiches with extraordinary precision.
Computer hard drives look set to hold up to 1000 times more data, thanks to research at Griffith University using nanotechnology, the science of miniature machines.
Is has been reported that Hewlett-Packard will buy Compaq for an estimated $47.5 billion. Both the New York Times and Wall Street Journal have reported the deal, citing people close to the negotiations, but both companies have declined comment. Compaq Australia said it could not confirm or deny the reports.
Designed to simplify offline power supplies up to 15 W, the L6590 fully integrated power supply chip from STMicroelectronics integrates a 700 V power MOSFET switch, plus all the control circuits needed to build a converter using flyback, boost or forward topologies.
SanDisk and Toshiba America Components state that their FlashVision fabrication (fab)plant has gone into production of advanced flash memories.
Simplex and Toshiba have announced a semiconductor architecture with the potential to deliver simultaneous improvements of 10+% greater chip performance, 20+% less power consumption and 30+% more chips per wafer.
