—A fully-active low-noise amplifier (LNA) for ultra-wideband application is presented. Passive on-chip inductor of conventional LNA design is replaced by low-noise active inductor, significantly reducing the total chip area of the proposed CMOS LNA. The core LNA circuit is a cascoded common-source amplifier loaded with an active inductor. Two buffer stages(More)
This paper presents a four-stage CMOS distributed amplifier (DA) design implemented in standard 0.18 μm CMOS technology. The proposed design eliminates the need for transmission line capacitors and, consequently, uses significantly smaller spiral inductors compared with the previous designs. Using the minimum size inductor, the bandwidth of the amplifiers(More)
