Abstract
A transceiver includes a RF modulator, a filter circuit, a control circuit and a first DC offset compensation circuit. During a first calibration period, the control circuit controls the filter circuit to be connected to the RF modulator with a first phase sequence, such that the RF modulator outputs a first radio frequency signal. During a second calibration period, the control circuit controls the filter circuit to be connected to the RF modulator with a second phase sequence, such that the RF modulator outputs a second radio frequency signal. The second phase sequence is inverted with the first phase sequence. The control circuit is further configured to calculate a first DC offset generated from the filter circuit, and to control the first DC offset compensation circuit to compensate the first DC offset generated from the filter circuit.
