Abstract:
A device includes a main low noise amplifier (LNA) stage configured to amplify a single-ended communication signal, an auxiliary LNA stage coupled to the main LNA stage, the auxiliary LNA stage configured to cancel non-linear second order products generated by the main LNA stage, and a load circuit configured to receive an output of the main LNA stage and an output of the auxiliary LNA stage, the load circuit configured to convert the single-ended communication signal to a differential signal.
