Which limit arises from increased amplifier gain in a regenerative receiver circuit?

💡 Explanation

Uncontrolled oscillation results because positive feedback, intended to linearly amplify incoming signals via regeneration, exceeds a stability criterion; therefore the amplifier oscillates without any input signal, rather than linearly amplifying it, because the loop gain is too high.
