Patent attributes
A semiconductor device is provided, the device including a first detection section having a removal section to remove DC offset components included in each of an input signal and an output signal output from an amplification section that amplifies the input signal, and a correction section configured to perform correction to match phases of the input signal and the output signal from which the DC offset components have been removed, and to match gains of the input signal and of the output signal, the first detection section comparing a waveform of the input signal to a waveform of the output signal, and a second detection section to detect a mismatch between the DC offset component included in the input signal that is input into the removal section and the DC offset component included in the output signal that is input into the removal section.
