Low power low voltage operation is found to be the bottleneck of future CMOS system implementations. To comply with these constrains, a current reuse configuration is here reported to design UWB Low Noise Amplifiers (LNA). A resistive feedback topology is first proposed performing an 11.5 dB gain over a 2 to 9 GHz range. Consuming a 17 mW under 1.4 V, this circuit achieves a 4.45 dB minimum Noise...
A low noise amplifier (LNA) for ultra-wideband (UWB) systems operating in 3~5GHz frequency range is presented. The LNA circuit is a cascade topology with inductively degeneration transistor. A new input impedance matching network based on monolithic transformers was proposed to overcome to the problem of broadband matching without degrading the noise performance and power delivery. The LNA achieves...
