Abstract
A half bridge GaN circuit is disclosed. The half bridge GaN circuit includes a first power node having a first power voltage, where the first power voltage is referenced to a switch voltage at the switch node. The half bridge GaN circuit also includes a VMID power node having a VMID power voltage, where the VMID power voltage is referenced to the first power voltage and is less than the first power voltage by a DC voltage. The half bridge GaN circuit also includes a logic circuit, where a negative power terminal of the logic circuit is connected to the VMID node, and where a positive power terminal of the first logic circuit is connected to the first power node, where the logic circuit is configured to generate a logic output voltage, which controls the conductivity of the high side power switch.
