摘要：
A tapered cascaded multi-stage distributed amplifier (T-CMSDA) has been designed and fabricated in a 90nm digital CMOS process. The amplifier achieves a 3-dB bandwidth of 73.5 GHz with a pass-band gain of 14dB. This results in a gain-bandwidth (GBW) product of 370 GHz. The realized zero-dB BW is 83.5 GHz and the input and output matchings stay better than -9dB up to 77 and 94 GHz, respectively. The chip consumes an area of 1.5mm by 1.15mm while drawing 70mA from a 1.2V supply.
