Abstract
A wideband amplifier includes a first stage and a second stage. The first stage includes a transconductance transistor driven by an input signal through an input transformer. The transconductance transistor couples to a cascode transistor forming an output node for the first stage. The second stage couples the output node from the first stage through an output transformer to drive an output transistor.
