6kV isolated silicon carbide gate driver

STMicroelectronics has created a pair of isolated gate drivers for silicon carbide mosfets. Called STGAP2SiCS, they are capable of producing a gate-driving voltage up to 26V, and there is a 15.5V under-voltage lock-out to prevent under-driving. Dual input pins provide a choice of gate-drive signal polarity. Inputs are compatible with CMOS and TTL logic down to ...

Lensless IR spectral microscope identifies cancer

Scientists in France have demonstrated a lens-less infra-red spectral-imaging system for medical diagnostics, obtaining simultaneously morphological and biochemical information. Images at different wavelengths differentiate tumour cells “The combination of a set of lasers and lens-less imaging with an uncooled bolometer matrix allows biochemical mapping over a wide field of view,” said Grégoire Mathieu of Grenoble ...
