Abstract :
A bi-quadrature down-conversion mixer with improved topology from 6 GHz to 9 GHz for MB-OFDM UWB application is presented in this paper. The mixer improves conversion gain of previous similar construction a lot and demonstrates a conversion gain of 14.0˜14.8 dB, Noise Figure (NF) of 15.1˜17.0 dB, and IIP3 of -15.0˜-13.9 dBm. The power dissipation is 19.8 mW under a supply voltage of 1.8 V in 0.18 μm CMOS technology, and the die size is 0.6 mm*1.1 mm.
