    摘要: A DC offset cancel circuit includes, in each of an I-channel side and a Q-channel side, a mixer and an ADC that output differential signals. The DC offset cancel circuit further includes a direct-current component extractor. The direct-current component extractor extracts direct-current components from a signal I and a signal Ib output from the mixer in the I-channel side and a signal Q and a signal Qb output from the mixer in the Q-channel side. The ADC in the I-channel side receives signals in which the direct-current components extracted from the signal Q and the signal Qb are fed forward to the signal I and the signal Ib. The ADC in the Q-channel side receives signals in which the direct-current components extracted from the signal I and the signal Ib are fed forward to the signal Q and the signal Qb.

    摘要: A frequency dividing phase shift circuit includes a first frequency divider and a second frequency divider. The first frequency divider is configured to perform 1/(2n+1) (n is a natural number) frequency division on an input signal having a frequency of (freq*2(2n+1)) (“freq” indicates a frequency) to generate a first signal having a frequency of (freq*2). The second frequency divider is configured to perform ½ frequency division on the first signal to generate 4-phase signals which are different in phase by 90 degrees one after another.
