Abstract:In this paper, A CMOS low noise amplifier (LNA) with an integrated notch feedback for interferer cancellation is presented. The proposed LNA adopts the integrated tunable notch feedback stage to cancel interferer signals at the input of the LNA, which eliminates the need of an off-chip filter. To improve the quality factor of the LC resonators, Q-enhancement circuit is used in the notch feedback stage. The proposed LNA is designed in a 0.13 μm CMOS technology. The LNA with the integrated notch feedback achieve… Show more
