Abstract:In this paper, a 3.5 GHz CMOS sub-harmonic mixer for LTE-advanced applications is presented. The mixer with the bulk-controlled technique improves the linearity and mitigates the power of the local oscillator. The proposed mixer is implemented by tsmc 0.18 μm Mixed Signal RF CMOS 1P6M process and consumes 2.2 mA from a 1.2 V supply. The proposed mixer operates at 3.5GHz LTE-advanced bands and achieves maximum input third-order intercept point (IIP3) of 2.3dBm, power conversion gains of 1.3 dB.
