A CMOS MedRadio Receiver RF Front-End With a Complementary Current-Reuse LNA
TL;DR: In this paper, a single-ended complementary current-reuse low-noise amplifier (CCRLNA) is proposed that achieves a power gain of 20 dB, noise figure (NF) of 2.8 dB, IIP3 of -8.1 dBm, and second-order intercept point of +34 dBm while consuming only 150 μW at 1-V supply voltage.
