  • Power supply enable circuit
    Patent number: 11467640
    Abstract: Disclosed is a power supply enable circuit. The power supply enable circuit includes a multi-input NAND gate, input terminals of the multi-input NAND gate respectively connected to a plurality of activation signal sources; and a delay circuit, an input terminal of the delay circuit electrically connected to a shared activation signal source of the plurality of activation signal sources. An output terminal of the delay circuit is electrically connected to an enable input terminal of a power supply circuit after performing a logical AND with an output terminal of the multi-input NAND gate.
