Abstract :
This paper presents the design and analysis of a down-conversion mixer for TD-SCDMA/LTE/LTE-Advanced application between 1.8-2.6 GHz. The proposed mixer is based on double-balanced Gilbert cell for its well-balanced performances. Designed in 0.18-μm process, the mixer achieves a conversion gain(CG) of 3.28-3.64 dB, a single sideband noise figure(NF) of 7.92-8.05 dB, and an input third-order intercept point(IIP3) of 4.4-4.68 dBm between 1.8-2.6 GHz. No inductor is employed in this circuit to reduce the circuit size, and the area of the core mixer layout is 0.147mm×0.132mm, while the area of total chip is 0.575mm×0.560mm.
