Abstract :
A low-voltage high-gain double-balanced mixer for direct-conversion ultra-wideband (UWB) receiver based on CMOS 0.18 μm process is presented in this paper. The conversion gain of the proposed mixer is mainly boosted by current mirror technique and RF leakage-resonant technique. Measured results of the proposed mixer exhibit the conversion gain of 12.38 dB to 15.69 dB and the third-order intercept point (IIP3) of -5 dBm to -1.64 dBm in the UWB range from 3 GHz to 5 GHz, while it consumes 7.2 mW under only 1.2 V supply voltage. The chip size including pads is 0.9 mm2.
