摘要
Methods, systems, and apparatus to increase common-mode transient immunity in isolation devices is disclosed. An example apparatus includes a current mirror including an input terminal and an output terminal; a transistor including a gate terminal, a first current terminal, and a second current terminal, the gate terminal coupled to a reference voltage terminal, the first current terminal coupled to the input terminal of the current mirror, and the second current terminal coupled to an input node; a buffer including an input terminal and an output terminal, the input terminal of the buffer coupled to the output terminal of the current mirror; and a logic gate including an input terminal and an output terminal, the input terminal of the logic gate coupled to the output terminal of the buffer.
