A wideband low-noise amplifier (LNA) based on the current-reused cascade configuration is proposed. The wideband input-impedance matching was achieved by taking advantage of the resistive shunt―shunt feedback in conjunction with a parallel LC load to make the input network equivalent to two parallel RLC-branches, i.e., a second-order wideband bandpass filter. Besides, both the inductive series- and shunt-peaking techniques are used for bandwidth extension. Theoretical analysis shows that both the frequency response of input matching and noise figure (NF) can be described by second-order functions with quality factors as parameters. The CMOS ultra-wideband LNA dissipates 10.34-mW power and achieves S11 below ―8.6 dB, S22 below ―10 dB, S12 below ―26 dB, flat S21 of 12.26 ± 0.63 dB, and flat NF of 4.24 ± 0.5 dB over the 3.1―10.6-GHz band of interest. Besides, good phase linearity property (group-delay variation is only ±22 ps across the whole band) is also achieved. The analytical, simulated, and measured results agree well with one another.
