摘要：
An ultra-wideband (UWB) CMOS low noise amplifier (LNA) topology that combines a narrowband LNA with a resistive shunt-feedback is proposed. The resistive shunt-feedback provides wideband input matching with small noise figure (NF) degradation by reducing the Q-factor of the narrowband LNA input and flattens the passband gain. The proposed UWB amplifier is implemented in 0.18-mum CMOS technology for a 3.1-5-GHz UWB system. Measurements show a -3-dB gain bandwidth of 2-4.6 GHz, a minimum NF of 2.3 dB, a power gain of 9.8 dB, better than -9 dB of input matching, and an input IP3 of -7 dBm, while consuming only 12.6 mW of power.
