Title: Wideband LNA Post by RF_Guy on Feb 22nd, 2006, 11:40am Anyone knows how to design a wideband LNA? Any good resource? |

Title: Re: Wideband LNA Post by aaron_do on Jul 26th, 2006, 7:17pm 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...
