A 3rd-order intermodulation (IM3) cancellation technique using a sub-mixer is proposed for low-power, low-distortion mixers. The technique reduces IM3 by 18dB with a current increase of less than 10%. The mixer achieves an IIP3 of 10dBm, a gain of 8.7dB, a NF of 9.8dB and dissipates 30mW from 2.9V.
