The first broadband amplifier using vertical inductors

Researchers at the Dresden University of Technology in Germany have proposed the first broadband amplifier using vertical inductors. All circuits are built from passive components, and improved chip design requires passive-component ...

A bright future for LEDs

A single wafer-level LED chip that produces more than 150 Watts of light output has been made in work form China. This level of output from a single chip makes applications for LEDs in high power lighting from stadiums to ...

New technology reduces size of spinal stimulator implants

Spinal cord stimulator implants could use less power and be made much smaller as work from Taiwan and Israel eliminates off-chip high-voltage devices from the implant's pulse generator. This will reduce implant-related discomfort ...

Q&A: Working towards 5G

Prof. Chenhao Qi of Southeast University, China, and Columbia University in the US, researches wireless communications technologies and sparse signal processing. Here, he talks about the significance of his paper 'Uplink ...

A single-sheet graphene p-n junction with two top gates

Researchers in Canada have designed and fabricated a single-sheet graphene p-n junction with two top gates. The standard technique, using a top and a bottom gate, can lead to damaging of the graphene layer. This is avoided ...

New oscillator for low-power implantable transcievers

Arash Moradi and Mohamad Sawan from Polytechnique Montreal in Canada discuss their new low-power VCO design for medical implants. This oscillator was implemented to provide the frequency deviation of frequency-shift-keying ...
