GaN Modules Boost Switching Frequencies While Maintaining Efficiency

In 2012, we finally got real insight into gallium-nitride (GaN) power devices. Efficient Power Conversion (ePC) published a 200-page textbook about the devices.1 If you want to understand how to compare figures of merit for GaN and silicon devices, for example, it’s there on page 24. International Rectifier (IR), meanwhile, disclosed the architecture of its first GaN products, the IP2010 …

Cryptography in software or hardware: It depends on the need

Cryptographic algorithms are high-performance, secure engines that require considerable space in a design. When countermeasures are added to thwart security attacks, the space and memory requirements grow even more demanding. For these reasons, cryptographic algorithms have traditionally been embedded as proprietary designs (i.e., intellectual property, IP) in hardware on smart cards or 8-bit chips. With recent improvements in core …
