The IP2 correction circuit is disclosed for controlling the second-order intermodulation of the direct conversion receiver mixer. IP2 correction circuit is a mixer, the first common mode feedback circuit, and a second common mode feedback circuit, and the current supply circuit. The mixer converts the direct radio input signal into a signal of a baseband. A first common mode feedback circuit has a common-mode negative feedback voltage of the output common mode voltage of the detection port, the detection of the mixer and to generate a common mode feedback voltage. Second detecting a common-mode feedback circuit includes a common mode voltage of the output port, and has a loop gain that changes in response to a gate control signal, which changes the impedance of the terminals of the output port. The current supply circuit in response to the common mode feedback voltage to supply a current to change to the output port of the mixer. Therefore, IP2 correction circuit to adjust the gain of the common mode feedback circuit to minimize the output voltage of the IM2, and can maximize the IP2, the small area occupied on a semiconductor wafer in the implementation of the semiconductor integrated circuit.
