Abstract
A first and a second transistor are connected to an output node. A first and a second differential amplifier compare a reference voltage with the voltage supplied from a voltage setting circuit. When the voltage at the output node is raised, the differential amplifier drives the first transistor, thereby charging the output node. In addition, when the voltage at the output node is lowered, the second differential amplifier drives the second transistor, thereby discharging the charges at the output node. The voltage setting circuit connected to the output node is composed of a current-summing D/A converter. In the voltage setting circuit, the value of the load resistance is varied according to the voltage appearing at the output node.
