Abstract :
In this paper a new highly linear CMOS mixer is proposed that utilizes simultaneously second and third-order distortion cancellation using second harmonic injection, and an in-depth analysis of the mixer is presented. Simulations in a 0.18 μm CMOS technology demonstrate that IIP3 and IIP2 of the proposed mixer have 10dB and 26dB improvements, respectively, compared with the conventional Gilbert-type mixer and the NF will not be degraded mainly. The mixer has a gain of 15 dB and 1.8V supply voltage, and current consumption is increased less than 1 mA in this technique.
