- A down-conversion active mixer for LTE receiver is proposed, which focus on improving the traditional sub-threshold compensation method. The linearity is improved by adjusting the load inductance of transconductance stage and optimizing the phase of third-order transconductance coefficient; the noise is reduced with current injection technology. The designed active mixer is simulated with TSMC 0.18 m 1P6M CMOS technology. The results show that: the mixer can be operated at the 1.4-3.6 GHz band, and with the IIP3 of 5.6~ 10.7dBm, the SSB NF ranges from 9.4 to 13.6 dB, the gain ranges from -0.25 to 3.4 dB, the power consumption is 14.1mW with supply of 1.5V. The proposed mixer also has a merit of low NF and high linearity.
