摘要

This paper presents an ultra-low-power (ULP) ultra-wideband low noise amplifier (LNA) for sub-GHz applications. A current reuse negative shunt feedback technique is employed to provide additional design freedom to lower the power consumption of the gm-boost common gate (CG) LNA. Fabricated in 90 nm CMOS technology, the LNA achieves a peak voltage gain of 14.2 dB with a 3-dB bandwidth of 930 MHz, a noise figure of 6.5 dB, and an IIP3 of -5.74 dBm, while consuming only 490 μW from a 1.2 V supply.
