Researchers in Austria have created quantum dots using two 2-d materials: graphene and hexagonal boron nitride. “For many applications in the field of quantum technologies one requires a quantum system were electrons occupy two states; on and off, similar to a classical switch, with the difference that quantum physics also allows for arbitrary superpositions of ...

Cypress Semi is providing the new Wi-Fi and bluetooth chip in Raspberry Pi’s Model B+, released last week. The chip is the CYW43455, which can operate 802.11ac Wi-Fi at 2.4 and 5GHz, as well as simultaneous Bluetooth and Bluetooth Low Energy (BLE). Prior to this, Raspberry Pi used the firm’s CYW43438 802.11n 2.4GHz Wi-Fi and Bluetooth combo. ...

Bosch has launched a 6 axis MEMS inertial measurement unit with a 3 axis 16bit accelerometer and 3 axis, 16bit gyroscope in a single package. Called BMI085, it is intended for virtual reality (VR) and augmented reality (AR) applications as well as navigation, body motion tracking and gaming. “Its ultra-precise instantaneous detection of head movements reduces ...

Toshiba has launched n-channel mosfet drivers for power switching the positive rail in rapid-charging and other load switching applications. Designed to drive a pair of back-to-back power mosfets (to block power flow in both directions), the devices include a charge-pump to provide gate drive above the positive rail. There are two parts, identical except for ...

Raspberry Pi 3 Model B+ is the highest performance Raspberry Pi yet, with its Brodcom BCM2837 now clocked at 1.4GHz instead of the Pi 3’s 1.2GHz. What has allowed the extra speed, according to Farnell, which has stock and is ready to ship the new board, is new flip-chip packaging for the main processor which, ...

To increase system-in-package integration density, Analog Devices is stacking die on a passives-on-silicon substrate using technology developed at its Limerick design centre. Dubbed iPassive, “this is a new thing in system-in-package”, ADI field application engineer Thomas Tzscheetzsch told Electronics Weekly at Embedded World in Nuremberg. “The passives are in the silicon, not in poly, real ...

US researchers have made on-chip inductors smaller by adding ‘kinetic inductance’ to conventional magnetic inductance. The work cuts the size of 10-50GHz inductors by a third. Kinetic inductance arises from the physical momentum of charge carriers resisting the change in current direction associated with a change in electric field, according to the team, from the ...

Silicon Labs revealed a Wi-Fi transceiver which consumes so little that it can be used in battery powered IoT sensor nodes, for example. Revealed at Embedded World, the WFM200 system-in-package (SiP, 6.5 x 6.5mm LGA52) consumes 200µA (average, delivery traffic indication message (DTIM)= 3). “We’ve delivered the first low-power Wi-Fi portfolio designed specifically for the ...

NXP was aiming at edge computing – data processing before transmission to the cloud – when it introduced the i.MX 8M family CPUS at Embedded World. Made on a 14LPC finfet process, versions with single, dual, and quad Arm Cortex-A53 running up to 2GHz were announced. The chips also include Cortex-M4 real-time processing at 400MHz. ...
