  • Second-order input intercept point (IIP2) calibration method of a mixer in a wireless communication system and the mixer using the same
    Patent number: 9276620
    Abstract: A mixer included in a receiver of a wireless communication system is provided. The mixer includes a switching unit including a plurality of transistors receiving a Radio Frequency (RF) signal and a Local Oscillation (LO) signal, and outputting a baseband signal, and a voltage controller outputting a voltage control signal controlling a body voltage of at least one transistor from among the plurality of transistors to thereby control a threshold voltage of the at least one transistor.
    Type: Grant
