Abstract

In this paper, we report on and compare coil designs for Gallium Nitride (GaN) smart power integration, where the power switch is monolithically integrated with Hall-effect sensor. A detailed geometry optimization study for a coil routed around a GaN Hall-effect magnetic sensor is presented for current monitoring applications. An electromagnetic 3-dimensional model examines the dimensions and configurations of the coil in a single or multiple turns for integration with a senseHEMT to galvanically monitor the current of the main power switch. Using concentric receiving zones on the sensor surface, the theoretical results demonstrate how coil designs affect the magnetic field spatial distribution. We use the MATLAB environment as an extensively adopted computing platform to electromagnetically simulate priory design the coils for GaN smart power integration.
