Rohm buys Renesas fab for IGBTs and MEMS

Rohm is spending Y450m buying Renesas’ 8inch Shiga fab.

After completing the deal, planned for February next year, which involves leasing the land and buildings, the line will mainly make IGBTs, mosfets and piezoelectric MEMS on a 0.15μm process, and will be Rohm’s main site for power…

Robot arm controlled by quadriplegic’s intentions

Californian researchers have linked a robot arm to the brain of a quadriplegic man, giving him smooth control over the arm.

The electrodes are not in the motor cortex or attached to muscle nerves, but are in a part of the brain associated with planning muscle activity: the posterior parietal…

1-26MHz MEMS oscillator challenges quartz on all fronts

Called SiT8021, power consumption is 110µA for 3MHz, and the device is available in chip-scale packages (CSPs) as small as 1.5×0.8mm.

The MEMS part is a 524kHz double tuning fork resonator (see diagram), identical to the one in a similar 32kHz oscillator released three months ago…

PCIM: Vicor slim-line PSU package takes double-sided cooling

Vicor has developed a slim-line power package for power supplies interfacing with ac or 380Vdc rails in data centres.

Called VIA (Vicor integrated adapter), it will come in various lengths and is 36mm wide and 9mm thick – so it will fit along the inside of a 1U chassis, or…

More on: IBM approaches 100Gbit/s all CMOS optical transceivers

IBM has revealed more about its 100Gbit/s CMOS optical transmitter, reported at the Conference on Lasers and Electro Optics in San Jose last week.

Using its sub-100nm CMOS9WG silicon-on-insulator process, it has implemented Mach-Zehnder modulators (MZMs) and a compatible 50Ω CMOS driver.

Unlike the 16Gbit…
