A simple and efficient "tool" for BiCMOS high performance RF process transistors evaluation

This paper presents a simple and efficient tool for fast evaluation of high performance BiCMOS RF process transistors. From the manual circuit analysis and design point of view the huge amount of information regarding transistors used in RF IC design tends to obscure the basic design parameters and theirs dependence on bias and lay-out details. Therefore it is worth and rewarding to build up a dedicated "tool" that helps the designer to evaluate "on the spot" some key electrical data sheets parameters. The "tool" consists of an evaluation circuit that allows setting the desired values for the transistors under test both static and dynamic operation parameters. This "tool" assists the designer in choosing the appropriate transistor for a given application.
