Claim 3:
4. The positive feedback latch amplitude limiting control circuit of the RFID tag according to claim 1, wherein: the signal processing circuit includes a detector circuit formed by at least one unidirectional conduction threshold device and a capacitive device, a first inverting sub-module INV1 and a second inverting sub-module INV2, wherein: an output terminal of the detector circuit is connected to a latch flip-flop with positive feedback characteristic formed by connecting an output terminal of the first inverting sub-module INV1 and an input terminal of the second inverting sub-module INV2, and connecting an input terminal of the first inverting sub-module INV1 and an output terminal of the second inverting sub-module INV2; and the signal processing circuit converts an analog signal to a digital signal, and is configured to: rapidly convert the first control signal S1 into a high-level or low-level logic signal according to an analog voltage amplitude of the first control signal S1, obtain the processed logic signal S2, and return the logic signal S2 to the signal generating circuit.
