N2 - In this paper, a novel digital base-band post-distorter is proposed to compensate for nonlinearities in low noise amplifiers. Though high gain, good input matching and low noise (low noise figure) are important factors, linearity and low power combined with these factors is most desirable. The proposed post-distorter achieves these factors by an indirect learning architecture at base-band to compensate for nonlinearities. The low noise amplifier was designed in the standard 0.18μm CMOS technology. It achieved a 8dB improvement in linearity with respect to the input power.
