Claim 13:
14. The driver circuit of claim 10, wherein the dead time control circuit further includes a clamper MOSFET having a P-type conductivity type, wherein the clamper MOSFET is coupled to the sensor MOSFET in series, wherein a gate of the clamper MOSFET is coupled to a bias voltage to clamp the dead time signal, wherein: the bias voltage is a voltage at a phase node, wherein the phase node is coupled between the high side MOSFET and the low side MOSFET; or the bias voltage is generated by a MOSFET diode which is connected in series between an input voltage of the input power and the gate of the clamper MOSFET.
