  • Abstract
    A variable gain LNA with large and continuous gain variation is proposed. By adding a simple gain-control loop at the second stage of a cascade LNA, a continuous gain tuning range of 28 dB is achieved. The maximum gain and NF of the LNA are 19 dB and 2.1 dB, respectively, while the DC power consumption is 13.5 mW.
