Printed circuit board (PCB) layout has been an integral aspect of power electronic design since the first switching power supplies appeared more than 40 years ago. Regardless of the transistor technology, the parasitic impedances added to the circuit by the PCB layout must be understood and managed for the circuit to function correctly, reliably, and without causing undue … [Read more...] about Optimizing PCB Layout for HV GaN Power Transistors

Practical Considerations for Design and Layout of High Power Digital PCBs: Reliably Powering Complex Multilayer Digital Printed Circuit Boards
This article discusses practical aspects of powering complex multilayer digital printed circuit boards (PCBs) from high-energy sources and tradeoffs that are required to make functional and reliable boards. What can be found between two layers of copper in a multi- layer PCB? Most engineers would say dielectric or isolation. Evidently not only that but, according to … [Read more...] about Practical Considerations for Design and Layout of High Power Digital PCBs: Reliably Powering Complex Multilayer Digital Printed Circuit Boards
