Multiple power domain electronic device and related method

摘要

An electronic device includes a first circuit, a second circuit, and a power on control (POC) circuit. The POC circuit includes an enable terminal electrically connected to a first output of the first circuit, a first input terminal electrically connected to a first voltage supply, a second input terminal electrically connected to a second voltage supply, and an output terminal. The second circuit includes a biasing-sensitive circuit, and a logic circuit including a first input terminal electrically connected to a second output of the first circuit, a second input terminal electrically connected to the output of the POC circuit, and an output terminal electrically connected to an enable terminal of the biasing-sensitive circuit.
