A 12mW 5GHz wideband low-noise amplifier in 0.13μm CMOS using noise cancellation

Abstract

This paper presents a wideband low-noise amplifier (LNA) exploiting noise cancellation technique, which operates at 800MHz-5.7GHz for low-power multi-standard applications. Implemented in a 0.13μm CMOS technology, the measured results of the LNA demonstrate the maximum gain of 11.7dB in the frequency range of 811MHz∼5.7GHz, the noise figure of 2.58∼5.11dB within the bandwidth, the input-referred third order intercept point (IIP3) of 1.6dBm at 2.4GHz, and the power consumption of 12mW from a single 1.2V supply. The chip occupies the total area of 0.7×0.9mm2. © 2011 IEEE.
