Dean Takahashi at VentureBeat profiles Alex Lidow. Silicon chips have had a decades-long run as the foundation for modern electronics. But a new kind of chip, based on the compound material gallium nitride (GaN), promises to unseat silicon because it has higher performance, less power consumption, and lower cost.

Enhancement-mode gallium nitride (GaN) transistors have been commercially available for over five years. Commercially available GaN FETs are designed to be both higher performance and lower cost than state-of-the-art silicon-based power MOSFETs. This achievement marks the first time in 60 years that any technology rivals silicon both in terms of performance and cost, and signals the ultimate displacement of the venerable, but aging power MOSFET.

Technics is back. Panasonic has unveiled the first new hi-fi products from the highly-regarded brand in 6 years. The new Reference Class system is made up of three components – a stereo power amp, a network audio control player and a speaker system. The amp uses a JENO Digital Engine to eliminate jitter and nip noise in the bud, and Load Adaptive Phase Calibration (LAPC) for flat amplitude-phase frequency delivery. It features GaN for high speed switching while keeping signal loss low, a proprietary digital link input, analog XLR input, analog RCA input, bi-wiring speaker terminals, and a silent linear power supply.

Long talked about, wide bandgap gallium nitride-on-silicon (GaN-on-Si) transistors are now commercially available. They are being touted for replacing silicon-based MOSFETs, which are turning out to be inefficient for many high-performance power supply designs. Recently, several suppliers of GaN-on-Si-based HEMTs and FETs have emerged in the marketplace, among them Efficient Power Conversion (EPC). To expedite the evaluation of eGAN FETs for power supply designs transitioning from silicon MOSFETs to eGaN FETs, EPC has released several development boards in the last few years.
