  • Patent number: 11456665
    Abstract: An electronic system device includes a semiconductor device and a power generating device for generating a power supply voltage. The semiconductor device includes a control circuit coupled with the power generating device via a power supply node, and a substrate-biased control circuit coupled with the control circuit. The electronic system device includes a DC-DC converter, and a switch arranged between the power supply nodes and the DC-DC converter. The control circuit sets the switch to an ON state after receiving the power supply voltage. The DC-DC converter receives the power supply voltage after the switch is controlled to the ON state. The substrate bias control circuit supplies a substrate bias voltage to the control circuit before the DC-DC converter receives the power supply voltage.
