Abstract
A signal output circuit including a first transistor coupled to a power supply line to receive a power supply voltage, a diode provided between the power supply line and a gate electrode of the first transistor, and a current generation circuit provided on a ground side with respect to the diode, the current generation circuit being configured to generate a current for the diode, upon turning on of the first transistor, and to increase the current, upon the power supply voltage dropping below a predetermined level.
