A 12dBm 320GHz GBW distributed amplifier in a 0.12/spl mu/m SOI CMOS

This paper describes a 9-stage distributed amplifier which achieves 11 dB gain and 90 GHz 3dB cut-off frequency, equivalent to a 320 GHz GBW. The measured 1 dB output compression point is 12 dBm at 20 GHz, the OIP3 is 15.5 dBm at 50 GHz, and the noise figure is 5.5 dB at 18 GHz.
