Abstract
A first power supply voltage input section can input a first power supply voltage, a second power supply voltage input section can input a second power supply voltage, a regulator circuit generates a back bias voltage on the basis of the second power supply voltage, and an output section can output the back bias voltage generated by the regulator circuit as an output voltage. A substrate bias can be generated with low power consumption, and the circuit scale can be reduced.
