With positive feedback.<\/p>\n<p>Latch-up is a destructive parasitic phenomenon that can occur in some integrated circuits (ICs) that contain complementary metal\u00e2\u0080\u0093oxide\u00e2\u0080\u0093semiconductor (CMOS) transistors. It is caused by a positive feedback loop that can occur when two or more CMOS transistors are connected in a particular way. This can lead to a sudden and uncontrolled increase in current, which can damage the IC.<\/p>\n<p>Positive feedback is a type of feedback in which the output of a system is fed back into the input in such a way that it amplifies the output. This can lead to a runaway situation in which the output of the system increases without limit.<\/p>\n<p>Negative feedback is a type of feedback in which the output of a system is fed back into the input in such a way that it counteracts the output. This can help to stabilize the system and prevent it from oscillating.<\/p>\n<p>No feedback is a type of feedback in which the output of a system is not fed back into the input. This can lead to instability in the system, as there is nothing to counteract the output.<\/p>\n<p>Without BJT is not a valid option, as latch-up can only occur in ICs that contain CMOS transistors.<\/p>\n<p>I hope this explanation is helpful.
