Abstract :
A new mixer linearization method is proposed, along with a method for optimizing an integrated inductor for a single balance mixer LO buffer with respect to power consumption and silicon area. With the proposed linearization technique and inductor optimization method, we can obtain a state-of-the-art low power 890 MHz cellular CDMA mixer compared with other published and commercially available products. The proposed mixer is fabricated in a 0.35 μm SiGe BiCMOS process and measurement results show 12 dBm IIP3 (third order input intercept point) and 10.2 dB conversion gain, and 7.5 dB SSB NF (single-sideband noise figure) with 10.5 mA current consumption at 2.7 V supply voltage.
