ABSTRACT:
In parallel to a first current source for discharging (or charging) a capacitive load in a complementary way with respect to a voltage output circuit, a second current source for compensating a voltage change caused by leak resistance is provided. Since the voltage change of the capacitive load caused by the leak resistance is not so large, the amount of a current let flow by the second current source provided for compensating the voltage change of the capacitive load caused by the leak resistance may be made smaller than the amount of a current let flow by the first current source. By providing the second current source, therefore, it becomes possible to compensate the voltage change of the capacitive load caused by leak resistance while limiting an increase in dissipated power to a very small value.
