Abstract
A driver is provided. The driver generally comprises a current source, a current mirror, an amplifier and a presetting circuit. The current source is generally adapted to provide a reference current to the current mirror. The transistor is coupled to the current mirror. The amplifier has the first input that is coupled to the current mirror, a second input that is coupled to a node between the transistor and the current mirror, and an output that is coupled to the control electrode of the transistor. The presetting circuit is coupled to the control electrode of the transistor so that it can preset the potential of the control electrode of the transistor to a potential that allows current driving of the transistor with a predetermined timing after a control signal is received.
