SECOND-ORDER INPUT INTERCEPT POINT (IIP2) CALIBRATION METHOD OF A MIXER IN A WIRELESS COMMUNICATION SYSTEM AND THE MIXER USING THE SAME

摘要

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.
