Abstract: One or more embodiments of a power circuit can comprise a capacitor in series between a power source and a gate of a transistor, to receive a driver output of a first voltage from the power source. The power circuit can further comprise a first diode in parallel between the power source and the gate of the transistor. In some embodiments, when the driver output is present and exceeds a first breakdown voltage of a second diode, and the second diode enables flow of current from the first cathode to the ground, resulting in the capacitor being negatively charged up to a second voltage corresponding to excess of the first voltage over the first breakdown voltage. In additional embodiments, after the capacitor is at least partially charged, when the driver output is not present, the capacitor discharges a negative current based on the negative charging of the capacitor up to the second voltage.
