Abstract
In one aspect, a gate driver circuit includes a gate driver having a first input connected to a first node and a second input connected to a second node. The gate driver circuit also includes a current source circuit that includes a first transistor and a capacitor having a top plate connected to the source of the first transistor and a bottom plate connected to ground. The gate driver circuit further includes a switch that includes a second transistor. A gate of the second transistor is connected to a drain of the first transistor and a source of the second transistor is connected to the first node.
