Hi,
for wideband i think you have the choice of a few different architectures like distributed amp (ultrawide band), common gate, resistive degeneration with shunt feedback, multiband (dual band etc).
For low power CMOS design I think a lot of groups published designs using the resistive degeneration with shunt feedback topology, but there are also a few common gate with stagger tunning which get good results. Common gate is also quite easy to design and I think has better bandwidth than the feedback topology.
see this paper for an idea of the design...
