Abstract
A filtering technique to remove out-of-band blockers in wireless receivers is presented. The circuit employs a feedforward filtering path to produce an arbitrarily narrow frequency response in the LNA, relaxing mixer linearity requirements. A prototype amplifier is implemented in a 65nm CMOS process. A stop-band rejection of over 21 dB is achieved.
