In this paper, a wideband fully integrated low-power and low-noise amplifier (LNA) is presented. It features an 8 GHz (from 4 GHz to 12 GHz) bandwidth and an excellent noise figure (NF) using 65 nm CMOS technology. This LNA was designed utilizing a current-reused technique and a cascode gain boost technique. In addition, the interstage inductors use series peaking to reduce the roll-off of high frequency gain and achieve high broadband gain. The proposed LNA circuit achieved high and flat power gain of 23.5±1 dB with input return loss less than -8 dB within the bandwidth of interest (4-12 GHz). The flat NF is 3.3±0.5 dB and the NFmin is a staggering 2.8 dB. Achieving the above performance, the third-order input point (IIP3) also reached -10.78 dBm, which is considered excellent. The LNA consumes 6.07 mW from a 1.2 V supply and occupies a layout area of 0.53x0.55 mm2 .
