Abstract:
     In an I/Q demodulation circuit, an offset amount determined in an offset detection mode is previously stored so that, in a normal reception mode, an offset is corrected for based on the data thus stored. With this configuration, a DC offset and a phase offset can be corrected for without a delay in an I/Q demodulation operation.
