Low-noise LDOs for Hi-Fi circuits up to 1A

Rohm has introduced ‘high-fidelity’ power supply ICs aimed at audio devices requiring high-resolution audio play-back. Above the quality of CD audio, it sees high-resolution audio sources typically playing back at “greater than 96kHz and 24bit”. Called the BD372xx series, the regulators have a newly-developed fast error amp circuit and low-noise architecture. “Multiple parameters that were ...

Unexpected spintronics reaction stores data

Data has been stored using a unexpected spin phenomenon. Now called ‘zero field switching’ (ZFS), it could be used in compact lower-power memory and computing devices, according to Johns Hopkins University and the US National Institute of Standards and Technology (NIST). The team discovered that magnetisation in a cobalt-iron-boron layer (see diagram) could be flipped ...

Tuneable quantum dots ride on graphene and BN

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 ...

Samsung sampling 8TB SATA SSD

Samsung is sampling an 8TB datacentre SATA SSD incorporating  LPDDR4 DRAM modules and features a 6.0-gigabits-per-second (Gbps) 2.5-inch SATA interface. “Our 64-layer V-NAND-based technology, allows us to double the capacity of current SATA storage,” says Samsung’s  Jim Elliott. The SSD uses  16Gb LPDDR4 DRAM based on 1xnm. A  SATA 3.3-compliant Power Disable (PWDIS) feature allows power ...

Softbank may IPO ARM

Softbank could IPO ARM, reports the FT, quoting Yoshimitsu Goto,a senior executive corporate officer at Softbank, saying “one possibility is re-listing ARM in the future”. Although vague, Goto’s statement contradicts the previously expressed views of Softbank boss Masa Son that Softbank’s intentions for ARM are long-term. Son had previously said that Softbank’s ownership of ARM ...
