I have Silicon carbide based vertical high-voltage JFET devices. I need to design driver circuit for them to use them in closed loop DC-DC power converter. Can anyone help me with the driver circuit design? The critical requirement is I need +1.25 V high and -10 V low swing. Negative swing is needed to turn-off the device properly as it's a JFET. I am not sure about the gate current requirement but I guess it will be not as big as a MOSFET gate drive requirement. Can I use one or two op-amps with +12 and -12 V bias to come up with the required +ve and -ve voltage outputs?
