Abstract:
A gate-charge harvester includes a harvest capacitor that has a first plate and a second plate. The second plate is coupled to a lower rail and the first plate is coupled to send a voltage towards a regulator. The gate-charge harvester also includes a low-side harvest transistor having a first terminal coupled to a gate of a low-side power transistor and a second terminal coupled to the first plate.
