Abstract :
A fully integrated RF front-end receiver for 3-5 GHz UWB application is reported. Low noise amplifier (LNA) adopts wide simultaneous noise and input matching technique to get better noise performance. Folded double balanced down conversion mixer is integrated with LNA implemented by 0.13 mum CMOS technology. Measured noise figure (NF) of each band (3432, 3960, and 4488 MHz) is 2.5, 3.3, and 4.2 dB at 100 MHz IF, respectively. Voltage conversion gain is measured as 19.4 dB to 23.5 dB. At the maximum gain band, -20 dBm IIP3 and -28 dBm PldB are measured. The total current is 14 mA from a 1.5 V supply.
