چکیده    By increasing the transceiver devices within the 3.1 to 10.6 ghz frequency band, the interferers and strong blockers from different equipment degraded the main received signals, so linearity performance becomes more notable. in this paper, a two path low noise amplifier (lna) is proposed for satisfying the overall efficiency of the ultra-wideband (uwb) radar used in vital sign detection, precise indoor localization, and high data rate wireless communications. a novel high linear circuit is recommended based on complementary derivative superposition (cds) and post distortion (pd) techniques. high pass filter and inductive source degeneration structured input impedance matching. post layout results of the designed uwb-lna in 180-nm cmos represented the average of third-order intercept point (iip3) is 8.1 dbm, s21 is 11 db and, s11 is below -10 db. the minimum noise figure (nf) is 3.11 db. the circuit draws 12.7 ma at 1.4-v. the chip area is 930 µm × 1090 µm. the proposed design in this work exhibits higher fom compared to similar lnas, it is clear, high-linearity performance in total bandwidth is an advantage compared to recent articles.
