Go-ahead for GaN

Go-ahead for GaN

It’s getting harder to avoid using GaN power transistors and ICs, says Alex Lidow. There are many reasons to use GaN-on-Si power transistors such as eGaN FETs, in telecoms, vehicles, healthcare and computing. Smaller, faster, lower cost, and more integrated, GaN-on-Si devices have spent a decade gaining the confidence and trust of designers across the spectrum of power conversion applications.

Qualifying and Quantifying GaN Devices for Power Applications

Qualifying and Quantifying GaN Devices for Power Applications

It’s okay to start using gallium-nitride (GaN) devices in your new designs. GaN transistors have become extremely popular in recent years. These wide-bandgap devices have been replacing LDMOS transistors in many power applications. For example, GaN devices are broadly being adopted for new RF power amplifiers used in cellular base stations, radar, satellites, and other high-frequency applications. In general, their ability to endure higher voltages and operate at frequencies well into the millimeter-wave (mmWave) range have them replacing traditional RF power transistors in most amplifier configurations.

The Race to Cut the Power Cord is Already Happening

The Race to Cut the Power Cord is Already Happening

The year is 2022. You sit down at your office desk, back from Ikea with your new lamp. You take it out of the box, place it on the table, and it illuminates the workspace immediately. You then take your MacBook out of your backpack, place it to the right of the lamp, and it starts charging instantly. It sounds unreasonable to think that all this could become reality in just a few years. But behind closed doors, this technology already exists.

“A couple of months ago, we demonstrated an entire table top where everything on it was powered wirelessly,” Alex Lidow, CEO of EPC, tells Inverse. “A lamp, computer monitor, computer, cell phones being charged… all sorts of stuff.”

Why a world without power cords is now within reach

Why a world without power cords is now within reach

Since Nikola Tesla first experimented with wireless power during the early 1900s, there has been a quest to “cut the cord” – and go wireless. Today’s applications for wireless power undoubtedly extend far beyond Tesla’s wildest imagination, as we now have the ability to wirelessly charge cell phones, power tools, and even buses while at their scheduled stops, not to mention airborne drones while flying. However, despite strong consumer and business demand for wireless charging, power cords still reign. What explains the lag in our ability to power all of our electronic devices and appliances wirelessly?

GaN FETs Drive Fidelity and Efficiency in Class-D Audio Amplifiers

GaN FETs Drive Fidelity and Efficiency in Class-D Audio Amplifiers

With the current maturity of Class-D audio amplifier architectures, amplifier fidelity and efficiency limitations are primarily at the device level. Silicon MOSFETs have been evolving for almost forty years, and their progress towards a perfect switch has slowed dramatically. There are some fundamental characteristics of MOSFETs that degrade sound quality and efficiency. In 2010, the enhancement mode Gallium nitride (GaN) power FET was introduced by Efficient Power Conversion (EPC), providing a large step towards the perfect switch.
