Abstract
In case an input voltage is zero, to sufficiently shut off an output current, a source side of a first transistor Tis connected to the drains of fourth and fifth transistors Tand T, and during a self-bias period of the first transistor T, a source of the first transistor Tis made a second potential through the fourth transistor T, and in a gate potential setting period of the first transistor Tby an input voltage Vin after the completion of the self-bias period, the source of the first transistor Tis made a third potential through the fifth transistor T
