A broadband low-noise front-end amplifier for ultra wideband in 0.13-/spl mu/m CMOS

A front-end amplifier for the Ultra Wideband (UWB) system is described. The amplifier has a single-ended input and a differential output, with 16 dB power gain, a flat-gain bandwidth of 2-5.2 GHz, an output 1-dB gain compression point of -8 dBm and a noise figure of 4.7-5.7 dB over the signal bandwidth. The amplifier is implemented in 0.13-/spl mu/m digital CMOS, occupies 0.4/spl times/0.6 mm/sup 2/, and consumes 38 mW.
