I&#39;m particularly interested in the overshoot, because controlling that is one of the claimed advantages of GaN technology. ...en-USTelligent Community 12https://community.element14.com/members-area/personalblogs/b/blog/posts/high-voltage-gan-fets---part-3-probing-the-lmg3410-half-bridgeThu, 25 Aug 2016 11:58:29 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:41e99c3c-8f4e-49d8-89ec-43d08635cb0ajc20483<p>Good stuff, Jan. Thanks for posting this.</p><p>&nbsp;</p><p>The high side FET anticipates the input signal and turns off 50nS before it arrives? Something tells me that might not be right.
