Technical memorandum: versatile strategy for CAD of multistage low-noise amplifiers

On the theoretical limits of noise-gain-mismatch tradeoff in the design of multi-stage cascaded transistor amplifiers

“…We focus here on available power gain instead of transducer power gain since a perfect match at the output port is assumed [6].…”

“…[1][2][3][4]) and is nowadays a text-book topic. This fact can generate the feeling that also the optimal multi-stage design problem has been thoroughly investigated and solved ( [5][6][7]). This feeling is also strengthened by the fact that, even at the higher microwave frequencies, the powerful computer-assisted optimization-based design software tools currently available in the market usually permit to achieve, without too much hassle, good performances in most practical cases.…”
