A 0.5-8GHz LNA and an 8-15GHz LNA connected by the active switch used in the Ultra-Wideband (UWB) reconfigurable receiver are presented in this paper. The common drain stage and resistance negative feedback technology as well as the source degeneration inductive technology are introduced to achieve a high flat gain and fine input matching. The current-reused technique is adopted to improve the gain and the noise characteristics. The 0.5-8GHz LNA I achieves a high flat gain of 22.32-24.56 dB, a noise figure (NF) of 3.69-4.52 dB and the S11 batter than -10.78 dB across the band. The 8-15GHz LNA II achieves a high flat gain of 24.3-26.59 dB, a NF of 3.80-4.51 dB and the S11 batter than -12.56 dB in the frequency band. |
