Classification: CPC G  H | IPC G  H

Claim 7:
8. A signal isolation method, comprising:
outputting, by a power management unit, a first signal to a digital logic circuit when power down is detected in a first circuit area, and outputting a second signal to the digital logic circuit when no power down is detected in the first circuit area;
performing, by the digital logic circuit, logical processing on the first signal received from the power management unit before outputting an isolation signal to an isolation circuit, and performing logical processing on the second signal received from the power management unit before outputting a connection signal to the isolation circuit; and
simultaneously receiving, by the isolation circuit, an interactive signal from the first circuit area and the isolation signal from the digital logic circuit, and blocking the interactive signal, or simultaneously receiving the interactive signal from the first circuit area and the connection signal from the digital logic circuit, and outputting the interactive signal to a second circuit area after the interactive signal is processed through voltage stabilization,
wherein the interactive signal comprises a data signal, and the receiving, by the isolation circuit, the isolation signal/connection signal from the digital logic circuit comprises receiving, by the isolation circuit, the isolation signal/connection signal from the digital logic circuit through a buffer module.
