  • Patent number: 10447257
    Abstract: Related-art back bias generation circuits cause a problem where a long time is required for transition between an operating state and a standby state because driving power is lowered to reduce the power consumption in the standby state. A back bias generation circuit outputs a predetermined voltage. The predetermined voltage is the back bias voltage of a substrate in a standby mode. A bias control circuit stores an electrical charge while a circuit block is in an operating mode, supplies the stored electrical charge to the substrate of a MOSFET included in the circuit block when the circuit block transitions from the operating mode to the standby mode, and subsequently supplies the output of the back bias generation circuit to the substrate of the MOSFET.
