Abstract
We present an active cancellation technique for removing the LO leakage signal at the input of the LNA in order to improve the IP2. The proposed method is implemented in a 65nm GSM/EDGE single chip radio and dramatically improves the IIP2 of the receiver by cancelling the static RF leakage at the input of the RF amplifiers.
