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.
