    Abstract

    A negative impedance is used to enable distortion cancellation between the transconductor and the cascode transistor for LNAs with a cascode topology. As a proof of concept, a resistive feedback LNA using this IM3 cancellation technique in a standard 0.16μm CMOS process shows that for 0.1GHz to 1GHz, improvements of 6.3dB to 10dB for IIP3 and 0.2dB to 1dB for gain are achieved without noise degradation. The power consumption for the LNA is increased by 2%, and the die area by about 700μm2.
