  • Automatic mismatch calibration circuit and method, and radio frequency receiver system
    Patent number: 11159254
    Abstract: The present disclosure provides an automatic mismatch calibration circuit and method, and a radio frequency receiver system. The automatic mismatch calibration circuit includes: at least one direct current (DC) offset estimation and calibration module coupled to a rear end of a radio frequency (RF) receiver to estimate a DC offset of received signals transmitted in an I channel and a Q channel to obtain an I-channel-DC-component and a Q-channel-DC-component, and compensate the I-channel-DC-component and the Q-channel-DC-component to the received signals corresponding to the I channel and the Q channel to achieve DC offset calibration. The present disclosure solves the problem that the existing mismatch calibration circuit cannot meet the low power consumption requirements of the system.
    Type: Grant
