Charge Pump Gate Driver Circuit with an Adjustable Pump Voltage for Active DV/DT Control

A charge pump gate driver circuit that provides an adjustable pump voltage level to achieve the active dv/dt control for wide bandgap devices.  The driver circuit has two power supplies, which provides positive and negative reference voltages, two separate charge pump circuits with two capacitors, and a typical totem-pole drive with two decoupling capacitors.  This achieves an online and active dv/dt regulation and eliminates extra power supplies to reduce cost and associated footprint.
