Low Power Ultra Wideband Up-conversion Mixer in CMOS 0,13 µm Technology

International audienceThis paper presents a low power, UWB up-conversion mixer, designed on CMOS 0.13 µm technology. This circuit is based on a double balanced Gilbert topology, which uses a feedback loop in its transconductance stage; in order to match the IF input impedance over a 10-510 MHz frequency range. This mixer exhibits a 0 dB conversion gain, a 7 dB noise factor, a DC power in the range of 4.2 mW and can output an RF signal over the 6-8.5 GHz frequency range
