Morphology
The phrase is largely compositional: a learner who knows 'circuit' and understands 'feedback' as output returned to input can infer this refers to a circuit where the feedback acts in a 'negative' (opposing or subtracting) way. However, the technical sense of 'negative' (meaning opposing/reducing the input) may not be obvious to a B1 learner who might read 'negative' only as 'bad', so the exact functional implication requires some prior exposure.
Etymology
The term negative feedback circuit comes from the simple image of a circuit that sends some of its output back as feedback that is negative, meaning it 'subtracts' from the input. That returned, opposing signal 'reduces' changes and helps keep the device's output steady, so the name explains why it 'stabilizes' the signal.
