Half bridge coupled resonant gate drivers

A circuit comprising:

• a first switching circuit having a first switch-driving terminal configured to be coupled to a gate node of a first switching transistor;
• a first inductor coupled to the first switching circuit;
• a second switching circuit having a second switch-driving terminal configured to be coupled to a gate node of a second switching transistor;
• a second inductor having a first terminal coupled to a second internal node of the second switching circuit and a second terminal coupled to the second switch-driving terminal of the second switching circuit, wherein the second inductor is magnetically coupled to the first inductor.
