Contemporary multistandard receivers implement the LNA functionality with either broadband LNAs, multiple separate LNAs or multiband LNAs. For system linearity, integration and area consumption, a multiband LNA could be preferable. This work demonstrates a switchable, 2.4-and-5 GHz dual-band feedback LNA, on an area as low as 40times160 mum2. Over 20 dB of gain is attained for a NF of 2.1 dB and a...
The need for a high level of integration in wireless and multi-standard radios, as well as the expensive area in downscaled CMOS pushes towards low-area circuit solutions. Feedback-type inductorless LNAs are such an example. This paper demonstrates a bondpad-size feedback type narrowband LNA using only one stacked inductor. The gain is 20.8 dB at 3.4 GHz with a noise figure of 2.2 dB. This solution...
