Abstract

A 0.7V low power LNA combines a 1:3 frontend balun with dual-path noise and non-linearity cancellation for improved noise performance at low power. In traditional techniques only the noise of the main path is cancelled while the noise of the auxiliary path is minimized by using high power. In the proposed design, the noise and non-linearity of both the main and the auxiliary paths are mutually cancelled allowing for low power operation. The 2.8dB NF, -10.7dBm IIP3 LNA in TSMC's 65nm GP process consumes 475μW of power resulting in an FOM of 28.8dB which is 8.2dB better than the state of the art.
