The invention discloses a current-mirror-type wireless telephone application (WTA) sensitive amplifier, which relates to the technical field of an amplifier in an integrated circuit, and comprises a current transmission circuit for detecting current difference on a bit line and a feedback amplification circuit for amplifying the current different to a voltage signal, and the current-mirror-type WTA sensitive amplifier also comprises a current mirror feedback circuit which is used for further amplifying the voltage signal by increasing the current difference. The current mirror structure is adopted to additionally introduce an additional feedback mechanism, so compared with the present WTA sensitive amplifier, the work speed of the circuit can be improved under the situation that the power consumption delay product of the circuit is not influenced.
