Abstract
In order to realize a reference voltage circuit that operates with lower current consumption while maintaining an operation at lower voltage without causing deterioration of a power supply rejection ratio, provided is a reference voltage circuit in which a depletion transistor of an ED type reference voltage circuit is constituted of a plurality of depletion transistors connected in series, and in which a gate terminal of a cascode depletion transistor is connected to a connection point between the depletion transistors of the ED type reference voltage circuit.
