University of Hong Kong researchers have used artificial intelligence to perform a brain scan with a conventional rare-earth magnet rather than a large superconducting magnet, and without a screened room. The ‘ultra-low field magnet’ – according to MRI nomenclature – was designed using almost 90kg of samarium cobalt as its field source – used because ...

Infineon has introduced a dual-channel smart gate driver for high-side load switches, design to control heavy loads in a 48 V board net through an SPI interface. Called 2ED4820-EM and ruggedised against vehicle transients, it can tolerate negative voltages at Vbat down to -90V and voltages up to +105V. Bus current sensing is included, with ...

STMicroelectronics is aiming at USB Power Delivery up to 60W (20V 3A) with a digitally programmable synchronous buck converter. Called STPD01, it will accept between 6 and 26.4V, and, controlled over I2C, deliver 3 to 20V in 20mV steps to meet PD specifications – with slew rate controllable up to 30mV/μs. Current can be set from ...

Texas instruments has revealed a buffer amplifier developed especially for oscilloscope inputs from dc to GHz. BUF802 signal paths “Oscilloscope manufacturers have got a choice: develop a discrete JFET input stage and risk limited performance, or develop their own asic,” TI general manager of linear amplifiers John Caldwell told Electronics Weekly. Developing a custom asic ...
