The note, AN005, picks a radiation-specified current-mode PWM controller from Texas Instruments (TPS7H5001-SP) as a source of PWM waveforms. Each TPS7H5001-SP can produce two pairs of upper and lower PWMs for a total of two phases, and TPS7H5001-SP has a mode that allows two ICs to be used in parallel to produce four pairs of […]

What sounds a bit like science fiction may actually not be so […]
Guerilla acquired all previously released components as well as new cores under development at Gallium Semiconductor. Additionally, all associated IP has been transferred to Guerrilla as part of this portfolio acquisition. “As the company continues to evolve as an RFIC and MMIC supplier, integrating GaN technology into our expanding portfolio is imperative,” says Guerrilla CEO Ryan […]

For example, nitrogen-vacancy (NV) centers in diamond have made breakthroughs […]
All commercial GaN power transistors are lateral current flow devices, including those already made by Power Integrations – technical limitations make vertical GaN devices very hard to make on a commercial scale. In a lateral device, source and drain contacts are on top of the semiconductor die, while vertical flow devices have source and drain […]
SureCore, the low power embedded SRAM specialist, has announced the successful tape out of an IC developed under the InnovateUK- funded project “Development of CryoCMOS to Enable the Next Generation of Scalable Quantum Computers”. This is a chip that will validate the cryogenic SPICE models and IP developed in the project that will be used […]
May 8, 2024 — Power Integrations recently announced an agreement to acquire the assets of Odyssey Semiconductor Technologies, a developer of vertical gallium-nitride (GaN) transistor technology. The transaction is expected to close in July 2024, after which all key Odyssey employees are expected to join Power Integrations’ technology organization. The acquisition supports the company’s ongoing development […]
By varying the chemical environment of the surface and applying electric fields from the scanning tunneling microscope tip, the authors can switch the material from a Mott insulator (with an energy gap) to an electrical conductor (without an energy gap). Credit: FLEET An Australian-led study has found unusual insulating behavior in a new atomically-thin material—and […]
