Abstrakt: This letter presents a differential two-stage cascode $D$ -band low-noise amplifier (LNA) using IHP’s $0.13~\mu \text{m}$ SiGe BiCMOS technology. Both gain-peaking and noise-reduction techniques are applied, and a proper interstage matching for an improved linearity is implemented and thereby, the best FoM is achieved among the reported silicon-based $D$ -band LNAs up to date. The small-signal gain is 20 dB at 140 GHz with a 3-dB bandwidth of 31 GHz. The LNA exhibits a simulated noise figure of 5.9 dB and an input-referred 1-dB compression point of −19.7 dBm, which demonstrates a leading-edge performance. The total occupied chip area is 0.4 mm2 including the pads, and the LNA core occupies only 0.1 mm2. The proposed differential LNA consumes a total of 31.8 mW from a 2-V supply. [ABSTRACT FROM AUTHOR]
