A 1.8V three-stage 25GHz 3dB-BW differential non-uniform downsized distributed amplifier

A three-stage nonuniform downsized distributed amplifier is realized in a 0.18/spl mu/m SiGe process, using CMOS transistors only. The amplifier achieves the differential forward gain of 7.8dB over a 25GHz bandwidth and an IIP3 of +4.7dBm. The 1.025/spl times/1.29mm/sup 2/ chip dissipates 54mW from a 1.8V supply.
