Abstract
A control voltage generating circuit according to an aspect of the present invention includes: a reference voltage unit that includes a plurality of first transistors of the same conductivity type connected in series between a first power supply and a second power supply, and generates a drain voltage of one of the plurality of first transistor as a reference voltage; and a voltage conversion unit that includes a plurality of second transistors connected in series between the first power supply and the second power supply and having the same conductivity type as that of the reference voltage, supplies the reference voltage to a gate of one of the plurality of second transistors, and outputs a drain voltage of one of the plurality of second transistors as a control voltage.
