A 0.5-8.5 GHz fully-differential CMOS RF distributed amplifier

Abstract

A fully-differential four-stage distributed amplifier (DA) with 5.5 dB gain and 8.5 GHz bandwidth has been integrated in 1.3 mm/spl times/2.2 mm in a 0.6 /spl mu/m digital CMOS process. The DA dissipates 216 mW from a single 3 V supply. A custom CAD tool was used to optimize the DA design including device and package parasitics.
