A 24-GHz High Linearity Down-conversion Mixer in 90-nm CMOS

Abstract

A 24-GHz high linearity down-conversion mixer in 90-nm CMOS is presented in this paper. The mixer utilizes folded architecture, LC tank, distributed derivative superposition (DS) linearization technique to achieve high linearity with relatively low power. The mixer achieves 0 dBm $\boldsymbol{IP}_{1\mathbf{dB}}$. The mixer provides −3 dB conversion gain and the IIP3 is 21 dBm with only 10-mW dc consumption.
