摘　　要：A wideband receiver RP front-end for IR-UWB applications is implemented in 0.13μm CMOS technology. Thanks to the direct sub-sampling architecture,there is no mixing process.Both LNA and VGA work at RF frequencies.To optimize noise as well as linearity,a differential common-source LNA with capacitive cross- coupling is used,which only consumes current of 1.8 mA from a 1.2 V power supply.Following LNA,a two-stage current-steering VGA is adopted for gain tuning.To extend the overall bandwidth,a three-stage staggered peaking technique is used.Measurement results show that the proposed receiver front-end achieves a gain tuning range from 5 to 40 dB within 6-7 GHz,a minimum noise figure of 4.5 dB and a largest IIP_3 of-11 dBm.The core receiver (without test buffer) consumes 14 mW from a 1.2 V power supply and occupies 0.58 mm^2 area.A wideband receiver RP front-end for IR-UWB applications is implemented in 0.13μm CMOS technology.
