Abstract
This paper presents a low noise down-conversion subharmonic mixer for Long-Term-Evolution Advanced (LTE-A) application. The proposed mixer adopts the bulk-driven to improve the switching speed of local oscillator (LO) stage and noise issue. This work exhibits the operating frequency of 3.51 GHz and the LO frequency of 1.75 GHz. The simulation results show the power conversion gain of 6.6 dB, single side-band noise figure (SSB NF) of 10.9 dB, and input second-order intercept point (IIP2) of 22 dBm. The mixer implemented by tsmc 0.18 μm CMOS process consumes 3.8 mA of current from a 1.5 V power supply.
