%X This paper presents a variable gain low-noise amplifier(VG-LNA) for 5 GHz applications.The effect of the input parasitic capacitance on the inductively degenerated common source LNA's input impedance is analyzed in detail.A new ESD and LNA co-design method was proposed to achieve good performance.In addition,by using a simple feedback loop at the second stage of the LNA,continuous gain control is realized.The measurement results of the proposed VG-LNA exhibit 25 dB(-3.3 dB to 21.7 dB) variable gain range,2....
