Noise canceling LNA with gain enhancement by using double feedback
We present a balun LNA with high gain and low noise figure by using active loads. A double feedback technique for gain enhancement and noise figure reduction is used. Two RF front-end receivers using a 130 nm CMOS technology were implemented: (1) using an LNA with active loads; (2) using an LNA with active loads and local double feedback.
