This article proposes a novel wideband common-gate (CG) common-source (CS) low-noise amplifier (LNA) with a dual complementary pMOS-nMOS configuration to provide a current-reuse output. Triple-path noise-cancellation is effectively revealed to eliminate the thermal noise of the two CG transistors. Simultaneously, partial cancellation of intrinsic third-order distortion of output-stage transistors improves the input third-order intercept point (IIP3). In addition, we embed a resistive feedback in one of the auxiliary CS amplifiers to balance the multiple tradeoffs between noise figure (NF), input matching (S), and forward gain (S). Fabricated in 65-nm CMOS, the proposed wideband LNA exhibits an IIP3 of 2.2-6.8 dBm and an NF of 3.3-5.3 dB across a 19-GHz BW while consuming 20.3 mW at 1.6 V. S is <-10 dB up to 23 GHz by designing a π-type input-matching network. The LNA exhibits a peak S of 12.8 dB and occupies a very compact die area of 0.096 mm
