Getting Ready for GaN CMOS

THE POWER ELECTRONIC CIRCUIT looks set to play an ever-increasing role in all our lives. It is needed in data centres, electric vehicles, cloud computing, and the internet of things.

Often, the performance of this type of circuit is far from ideal. Efficiency is below where it could be, and the circuit takes up much space, due to the use of bulky passive components, such as large inductors and capacitors. What’s needed is to move to more efficient transistors that switch at faster speed. Do this and many benefits result – as well as trimming the electrical losses associated with this device, a higher switching frequency allows the use of smaller passive components that shrink the size and weight of the circuit.  Read More
