    • A path gate driver circuit of the present invention includes a shunt stage, a level shifter stage, a pull-up stage, and an output stage. The shunt stage has a control terminal coupled to a supply, and an input terminal coupled to a control signal path. The level shifter stage has a first control terminal coupled to the control signal path, a second control terminal coupled to an output terminal of the shunt stage, a first input terminal coupled to a boost-low supply, and a second input terminal coupled to a boost-high supply. The pull-up stage has a control terminal coupled to an output terminal of the level shifter stage, and an input terminal coupled to the boost-high supply. The output stage has a first control terminal coupled to the output terminal of the shunt stage and an output terminal of the pull-up stage, a second control terminal coupled to the control signal path a first input terminal coupled to the boost-low supply, and a second input terminal coupled to the boost-high supply. A boosted control signal is provided at the output terminal of the output stage in response to the control.
