Abstract
A diving circuit drives an output transistor according to a control signal S. The gate of the first transistor is biased. The source of the first transistor is coupled to an internal line. In the on period of the output transistor, the voltage of the internal line is applied to a control electrode of the output transistor. A voltage correction circuit controls the internal line so as to gradually lower the voltage Vof the internal line with time.
