摘要
This paper presents a low noise amplifier (LNA) in 0.13 mu m CMOS for ultra-wideband (UWB) receiver. The LNA has a peak gain of 27 dB and a 3.0 - 10.7 GHz -3dB bandwidth. Its input impedance matching is better than -5 dB and output matching is less than -15dB. Its lowest noise figure (NF) is 0.4 dB and the average NF is 3 dB. The LNA achieves NFmin performance over the entire bandwidth by using a power-constrained simultaneous noise and input matching concept. It's power consumption is only 4.8 mW with a 1.2 V power supply, for amplifier core and 1.8 mW in output buffer. A comparison with recently published UWB LNA shows that this design exhibits the best overall performance in terms of gain, NF and power consumption.
